The remote Oracle Linux 5 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2013-1411 advisory.

    [2.5-118.2]
    - Fix integer overflows in *valloc and memalign. (#1011804).

    [2.5-118.1]
    - Add support for newer L3 caches on x86-64 and correctly count       the number of hardware threads sharing a cacheline (#1011424).

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

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

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.

It was discovered that the GNU C Library incorrectly handled the strcoll() function. An attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2012-4412, CVE-2012-4424)

It was discovered that the GNU C Library incorrectly handled multibyte characters in the regular expression matcher. An attacker could use this issue to cause a denial of service. (CVE-2013-0242)

It was discovered that the GNU C Library incorrectly handled large numbers of domain conversion results in the getaddrinfo() function. An attacker could use this issue to cause a denial of service.
(CVE-2013-1914)

It was discovered that the GNU C Library readdir_r() function incorrectly handled crafted NTFS or CIFS images. An attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2013-4237)

It was discovered that the GNU C Library incorrectly handled memory allocation. An attacker could use this issue to cause a denial of service. (CVE-2013-4332).

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

Updated glibc packages that fix three security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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.

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 Red Hat enterprise 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.
(BZ#1022022)

These updated glibc packages also include additional bug fixes and various enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.

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

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-1605 advisory.

    - Fix getaddrinfo stack overflow resulting in application crash (CVE-2013-1914, #951213).
    - Fix multibyte character processing crash in regexp (CVE-2013-0242, #951213).

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 remote VMware ESXi host is version 5.1 prior to build 2323236. It is, therefore, affected by the following vulnerabilities in bundled third-party libraries :

  - Multiple vulnerabilities exist in the bundled Python     library. (CVE-2011-3389, CVE-2012-0845, CVE-2012-0876,     CVE-2012-1150, CVE-2013-1752, CVE-2013-4238)

  - Multiple vulnerabilities exist in the bundled GNU C     Library (glibc). (CVE-2013-0242, CVE-2013-1914,     CVE-2013-4332)

  - Multiple vulnerabilities exist in the bundled XML     Parser library (libxml2). (CVE-2013-2877, CVE-2014-0191)

  - Multiple vulnerabilities exist in the bundled cURL     library (libcurl). (CVE-2014-0015, CVE-2014-0138)

The remote VMware ESXi host is version 5.5 prior to build 1623387. It is, therefore, affected by multiple vulnerabilities :

  - Multiple integer overflow conditions exist in the     bundled GNU C Library (glibc) due to improper validation     of user-supplied input. A remote attacker can exploit     these issues to cause a buffer overflow, resulting in a     denial of service condition. (CVE-2013-4332)

  - A flaw exists in the monlist feature in NTP. A remote     attacker can exploit this flaw, using a specially     crafted packet to load the query function in monlist, to     conduct a distributed denial of service attack.
    (CVE-2013-5211)

The remote NewStart CGSL host, running version MAIN 5.04, has glibc packages installed that are affected by multiple vulnerabilities:

  - elf/dl-load.c in ld.so in the GNU C Library (aka glibc     or libc6) through 2.11.2, and 2.12.x through 2.12.1,     does not properly handle a value of $ORIGIN for the     LD_AUDIT environment variable, which allows local users     to gain privileges via a crafted dynamic shared object     (DSO) located in an arbitrary directory. (CVE-2010-3847)

  - ld.so in the GNU C Library (aka glibc or libc6) before     2.11.3, and 2.12.x before 2.12.2, does not properly     restrict use of the LD_AUDIT environment variable to     reference dynamic shared objects (DSOs) as audit     objects, which allows local users to gain privileges by     leveraging an unsafe DSO located in a trusted library     directory, as demonstrated by libpcprofile.so.
    (CVE-2010-3856)

  - 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)

  - 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, CVE-2013-4458)

  - 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)

  - An out-of-bounds write flaw was found in the way the     glibc's readdir_r() function handled file system entries     longer than the NAME_MAX character constant. A remote     attacker could provide a specially crafted NTFS or CIFS     file system that, when processed by an application using     readdir_r(), would cause that application to crash or,     potentially, allow the attacker to execute arbitrary     code with the privileges of the user running the     application. (CVE-2013-4237)

  - 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)

  - 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)

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

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2013-658:03 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-2013-4332     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:
     Previously, the L3 cache size of some CPUs for SMP server was sometimes not correctly detected. This lead     to non-optimal performance and has been fixed.
     Added locking to compat_call() function to prevent multiple threads from racing.
     Previously, glibc could sometimes terminate unexpectedly with a segmentation fault when attempting to use     one dynamically-loaded character conversion routine. This has been fixed.
     The ftell() function was fixed to correctly set the internal FILE offset field for wide characters. The     ftell() and fseek() functions now handle offsets for wide characters correctly.
     A previous fix to prevent logic errors in mathematical functions caused performance regression for     certain inputs. This has been fixed.
     The nscd daemon no longer cache DNS entries with a TTL of zero and lookups for those entries return the     correct and current results.
     Applications running under low-memory conditions no longer terminate unexpectedly while calling     localization routines and now report errors if working in low-memory conditions.

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

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

Existing statically linked applications must be rebuilt to fix CVE-2013-4788.

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)
