According to the versions of the glibc packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - stdlib/canonicalize.c in the GNU C Library (aka glibc     or libc6) 2.27 and earlier, when processing very long     pathname arguments to the realpath function, could     encounter an integer overflow on 32-bit architectures,     leading to a stack-based buffer overflow and,     potentially, arbitrary code execution.(CVE-2018-11236)

  - An integer overflow vulnerability was found in     hcreate() and hcreate_r() functions which could result     in an out-of-bounds memory access. This could lead to     application crash or, potentially, arbitrary code     execution.(CVE-2015-8778)

  - A stack-based buffer overflow was found in the way the     libresolv library performed dual A/AAAA DNS queries. A     remote attacker could create a specially crafted DNS     response which could cause libresolv to crash or,     potentially, execute code with the permissions of the     user running the library. Note: this issue is only     exposed when libresolv is called from the nss_dns NSS     service module.(CVE-2015-7547)

  - A flaw was found in the regular expression matching     routines that process multibyte character input. If an     application utilized the glibc regular expression     matching mechanism, an attacker could provide     specially-crafted input that, when processed, would     cause the application to crash.(CVE-2013-0242)

  - A flaw was found in the way memory was being allocated     on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were     adjacent to each other, an attacker could use this flaw     to jump over the stack guard gap, cause controlled     memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on     the system. This is glibc-side mitigation which blocks     processing of LD_LIBRARY_PATH for programs running in     secure-execution mode and reduces the number of     allocations performed by the processing of LD_AUDIT,     LD_PRELOAD, and LD_HWCAP_MASK, making successful     exploitation of this issue more     difficult.(CVE-2017-1000366)

  - The DNS stub resolver in the GNU C Library (aka glibc     or libc6) before version 2.26, when EDNS support is     enabled, will solicit large UDP responses from name     servers, potentially simplifying off-path DNS spoofing     attacks due to IP fragmentation.(CVE-2017-12132)

  - It was found that the files back end of Name Service     Switch (NSS) did not isolate iteration over an entire     database from key-based look-up API calls. An     application performing look-ups on a database while     iterating over it could enter an infinite loop, leading     to a denial of service.(CVE-2014-8121)

  - Stack-based buffer overflow in the getaddrinfo function     in sysdeps/posix/getaddrinfo.c in the GNU C Library     (aka glibc or libc6) allows remote attackers to cause a     denial of service (crash) via vectors involving hostent     conversion. NOTE: this vulnerability exists because of     an incomplete fix for CVE-2013-4458.(CVE-2016-3706)

  - In glibc 2.26 and earlier there is confusion in the     usage of getcwd() by realpath() which can be used to     write before the destination buffer leading to a buffer     underflow and potential code     execution.(CVE-2018-1000001)

  - Stack-based buffer overflow in string/strcoll_l.c in     the GNU C Library (aka glibc or libc6) 2.17 and earlier     allows context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string that triggers a malloc failure and use of     the alloca function.(CVE-2012-4424)

  - It was found that the dynamic loader did not sanitize     the LD_POINTER_GUARD environment variable. An attacker     could use this flaw to bypass the pointer guarding     protection on set-user-ID or set-group-ID programs to     execute arbitrary code with the permissions of the user     running the application.(CVE-2015-8777)

  - The glob function in glob.c in the GNU C Library (aka     glibc or libc6) before 2.27 contains a buffer overflow     during unescaping of user names with the ~     operator.(CVE-2017-15804)

  - res_query in libresolv in glibc before 2.25 allows     remote attackers to cause a denial of service (NULL     pointer dereference and process crash).(CVE-2015-5180)

  - pt_chown in GNU C Library (aka glibc or libc6) before     2.18 does not properly check permissions for tty files,     which allows local users to change the permission on     the files and obtain access to arbitrary     pseudo-terminals by leveraging a FUSE file     system.(CVE-2013-2207)

  - A stack overflow flaw was found in glibc's swscanf()     function. An attacker able to make an application call     the swscanf() function could use this flaw to crash     that application or, potentially, execute arbitrary     code with the permissions of the user running the     application.(CVE-2015-1473)

  - It was found that getaddrinfo() did not limit the     amount of stack memory used during name resolution. An     attacker able to make an application resolve an     attacker-controlled hostname or IP address could     possibly cause the application to exhaust all stack     memory and crash.(CVE-2013-4458)

  - A heap-based buffer overflow was found in glibc's
    __nss_hostname_digits_dots() function, which is used by     the gethostbyname() and gethostbyname2() glibc function     calls. A remote attacker able to make an application     call either of these functions could use this flaw to     execute arbitrary code with the permissions of the user     running the application.(CVE-2015-0235)

  - Multiple integer overflow flaws, leading to heap-based     buffer overflows, were found in glibc's memory     allocator functions (pvalloc, valloc, and memalign). If     an application used such a function, it could cause the     application to crash or, potentially, execute arbitrary     code with the privileges of the user running the     application.(CVE-2013-4332)

  - An integer overflow in the implementation of the     posix_memalign in memalign functions in the GNU C     Library (aka glibc or libc6) 2.26 and earlier could     cause these functions to return a pointer to a heap     area that is too small, potentially leading to heap     corruption.(CVE-2018-6485)

  - A stack based buffer overflow vulnerability was found     in the catopen() function. An excessively long string     passed to the function could cause it to crash or,     potentially, execute arbitrary code.(CVE-2015-8779)

a. DDoS vulnerability in NTP third-party libraries

   The NTP daemon has a DDoS vulnerability in the handling of the    'monlist' command. An attacker may send a forged request to a    vulnerable NTP server resulting in an amplified response to the    intended target of the DDoS attack.       Mitigation

   Mitigation for this issue is documented in VMware Knowledge Base    article 2070193. This article also documents when vSphere    products are affected.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2013-5211 to this issue.

  b. Update to ESXi glibc package

  The ESXi glibc package is updated to version   glibc-2.5-118.el5_10.2 to resolve a security issue.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2013-4332 to this issue.

  c. vCenter and Update Manager, Oracle JRE 1.7 Update 45      Oracle JRE is updated to version JRE 1.7 Update 45, which   addresses multiple security issues that existed in earlier   releases of Oracle JRE. 

  Oracle has documented the CVE identifiers that are addressed   in JRE 1.7.0 update 45 in the Oracle Java SE Critical Patch   Update Advisory of October 2013. The References section provides   a link to this advisory.

Updated glibc packages fixes the following security issues :

Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow (CVE-2012-4412).

Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function (CVE-2012-4424).

pt_chown in GNU C Library (aka glibc or libc6) before 2.18 does not properly check permissions for tty files, which allows local users to change the permission on the files and obtain access to arbitrary pseudo-terminals by leveraging a FUSE file system (CVE-2013-2207).
NOTE! This is fixed by removing pt_chown wich may break chroots if their devpts was not mounted correctly (make sure to mount the devpts correctly with gid=5).

sysdeps/posix/readdir_r.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted (1) NTFS or (2) CIFS image (CVE-2013-4237).

Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions (CVE-2013-4332).

A stack (frame) overflow flaw, which led to a denial of service (application crash), was found in the way glibc's getaddrinfo() function processed certain requests when called with AF_INET6. A similar flaw to CVE-2013-1914, this affects AF_INET6 rather than AF_UNSPEC (CVE-2013-4458).

The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context- dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address (CVE-2013-4788).

Other fixes in this update :

  - Correct the processing of '\x80' characters in     crypt_freesec.c

    - fix typo in nscd.service

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2014-073:01 advisory.

    The glibc package contains standard libraries which are used by multiple programs on the system. In order     to save disk space and memory, as well as to make upgrading easier, common system code is kept in one     place and shared between programs. This particular package contains the most important sets of shared     libraries: the standard C library and the standard math library. Without these two libraries, a Linux     system will not function.
    Security issues fixed with this release:
     CVE-2013-0242     Buffer overflow in the extend_buffers function in the regular expression matcher (posix/regexec.c) in     glibc, possibly 2.17 and earlier, allows context-dependent attackers to cause a denial of service (memory     corruption and crash) via crafted multibyte characters.
     CVE-2013-1914     Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library     (aka glibc or libc6) 2.17 and earlier allows remote attackers to cause a denial of service (crash) via a     (1) hostname or (2) IP address that triggers a large number of domain conversion results.
     CVE-2013-4332     Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier     allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the     (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions.
    Fixed bugs:
     A defect in the initial release of the getaddrinfo() system call caused AF_INET and AF_INET6 queries to     return names queried from the /etc/hosts file as canonical names. This behavior is incorrect but it is the     expected behavior. However, a later change in the getaddrinfo() function made AF_INET6 queries return the     canonical name correctly but this was unexpected by applications relying on queries from the /etc/hosts     file and they could fail to operate properly. This update ensures that AF_INET6 queries resolved from     /etc/hosts always return the name as canonical. A proper patch might be issued when a standard is     establish. For now, the first entry on the /etc/hosts file should be considered the canonical entry.
     Previously, nscd sometimes failed to return both IPv4 and IPv6 addresses when querying for an address     using the AF_UNSPEC address family, even when both IPv4 and IPv6 results existed. This has been fixed.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This glibc update fixes a critical privilege escalation vulnerability and the following security and non-security issues :

  - bnc#892073: An off-by-one error leading to a heap-based     buffer overflow was found in __gconv_translit_find(). An     exploit that targets the problem is publicly available.
    (CVE-2014-5119)

  - bnc#886416: Avoid redundant shift character in iconv     output at block boundary.

  - bnc#883022: Initialize errcode in     sysdeps/unix/opendir.c.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated glibc packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc's memory allocator functions (pvalloc, valloc, and memalign). If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-4332)

This update also fixes the following bug :

* Prior to this update, the size of the L3 cache in certain CPUs for SMP (Symmetric Multiprocessing) servers was not correctly detected.
The incorrect cache size detection resulted in less than optimal performance for routines that used this information, including the memset() function. To fix this bug, the cache size detection has been corrected and core routines including memset() have their performance restored to expected levels. (BZ#1011424)

All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

This update for glibc contains the following fixes :

  - Fix integer overflows in malloc. (CVE-2013-4332,     bnc#839870)

  - Fix buffer overflow in glob. (bnc#691365)

  - Fix buffer overflow in strcoll. (CVE-2012-4412,     bnc#779320)

  - Update mount flags in <sys/mount.h>. (bnc#791928)

  - Fix buffer overrun in regexp matcher. (CVE-2013-0242,     bnc#801246)

  - Fix memory leaks in dlopen. (bnc#811979)

  - Fix stack overflow in getaddrinfo with many results.
    (CVE-2013-1914, bnc#813121)

  - Don't raise UNDERFLOW in tan/tanf for small but normal     argument. (bnc#819347)

  - Properly cross page boundary in SSE4.2 implementation of     strcmp. (bnc#822210)

  - Fix robust mutex handling after fork. (bnc#827811)

  - Fix missing character in IBM-943 charset. (bnc#828235)

  - Fix use of alloca in gaih_inet. (bnc#828637)

  - Initialize pointer guard also in static executables.
    (CVE-2013-4788, bnc#830268)

  - Fix readdir_r with long file names. (CVE-2013-4237,     bnc#834594)

Several vulnerabilities have been fixed in eglibc, Debian's version of the GNU C library.

#553206 CVE-2015-1472 CVE-2015-1473

The scanf family of functions do not properly limit stack allocation, which allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code.

CVE-2012-3405

The printf family of functions do not properly calculate a buffer length, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service.

CVE-2012-3406

The printf family of functions do not properly limit stack allocation, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string.

CVE-2012-3480

Multiple integer overflows in the strtod, strtof, strtold, strtod_l, and other related functions allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

CVE-2012-4412

Integer overflow in the strcoll and wcscoll functions allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow.

CVE-2012-4424

Stack-based buffer overflow in the strcoll and wcscoll functions allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function.

CVE-2013-0242

Buffer overflow in the extend_buffers function in the regular expression matcher allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters.

CVE-2013-1914 CVE-2013-4458

Stack-based buffer overflow in the getaddrinfo function allows remote attackers to cause a denial of service (crash) via a hostname or IP address that triggers a large number of domain conversion results.

CVE-2013-4237

readdir_r allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a malicious NTFS image or CIFS service.

CVE-2013-4332

Multiple integer overflows in malloc/malloc.c allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the pvalloc, valloc, posix_memalign, memalign, or aligned_alloc functions.

CVE-2013-4357

The getaliasbyname, getaliasbyname_r, getaddrinfo, getservbyname, getservbyname_r, getservbyport, getservbyport_r, and glob functions do not properly limit stack allocation, which allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code.

CVE-2013-4788

When the GNU C library is statically linked into an executable, the PTR_MANGLE implementation does not initialize the random value for the pointer guard, so that various hardening mechanisms are not effective.

CVE-2013-7423

The send_dg function in resolv/res_send.c does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.

CVE-2013-7424

The getaddrinfo function may attempt to free an invalid pointer when handling IDNs (Internationalised Domain Names), which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code.

CVE-2014-4043

The posix_spawn_file_actions_addopen function does not copy its path argument in accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after-free vulnerabilities.

For the oldstable distribution (squeeze), these problems have been fixed in version 2.11.3-4+deb6u5.

For the stable distribution (wheezy), these problems were fixed in version 2.13-38+deb7u8 or earlier.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote VMware ESX / ESXi host is affected by multiple vulnerabilities :

  - Multiple integer overflow conditions exist in the glibc     package in file malloc/malloc.c. An unauthenticated,     remote attacker can exploit these to cause heap memory     corruption by passing large values to the pvalloc(),     valloc(), posix_memalign(), memalign(), or     aligned_alloc() functions, resulting in a denial of     service. (CVE-2013-4332)

  - A distributed denial of service (DDoS) vulnerability     exists in the NTP daemon due to improper handling of the     'monlist' command. A remote attacker can exploit this,     via a forged request to an affected NTP server, to cause     an amplified response to the intended target of the DDoS     attack. (CVE-2013-5211)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc's memory allocator functions (pvalloc, valloc, and memalign). If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-4332)

A flaw was found in the regular expression matching routines that process multibyte character input. If an application utilized the glibc regular expression matching mechanism, an attacker could provide specially crafted input that, when processed, would cause the application to crash. (CVE-2013-0242)

It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker-controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash. (CVE-2013-1914)

Among other changes, this update includes an important fix for the following bug :

  - Due to a defect in the initial release of the     getaddrinfo() system call in Scientific Linux 6.0,     AF_INET and AF_INET6 queries resolved from the     /etc/hosts file returned queried names as canonical     names. This incorrect behavior is, however, still     considered to be the expected behavior. As a result of a     recent change in getaddrinfo(), AF_INET6 queries started     resolving the canonical names correctly. However, this     behavior was unexpected by applications that relied on     queries resolved from the /etc/hosts file, and these     applications could thus fail to operate properly. This     update applies a fix ensuring that AF_INET6 queries     resolved from /etc/hosts always return the queried name     as canonical. Note that DNS lookups are resolved     properly and always return the correct canonical names.
    A proper fix to AF_INET6 queries resolution from     /etc/hosts may be applied in future releases; for now,     due to a lack of standard, Red Hat suggests the first     entry in the /etc/hosts file, that applies for the IP     address being resolved, to be considered the canonical     entry.

This glibc update fixes a critical privilege escalation problem and the following security and non-security issues :

  - bnc#892073: An off-by-one error leading to a heap-based     buffer overflow was found in __gconv_translit_find(). An     exploit that targets the problem is publicly available.
    (CVE-2014-5119)
