According to the versions of the glibc packages installed, the EulerOS 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 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)

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

  - 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)

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6)     2.19 through 2.26 mishandles RPATH and RUNPATH     containing $ORIGIN for a privileged (setuid or     AT_SECURE) program, which allows local users to gain     privileges via a Trojan horse library in the current     working directory, related to the fillin_rpath and     decompose_rpath functions. This is associated with     misinterpretion of an empty RPATH/RUNPATH token as the     ./ directory. NOTE: this configuration of     RPATH/RUNPATH for a privileged program is apparently     very uncommon; most likely, no such program is shipped     with any common Linux distribution. (CVE-2017-16997)

  - A buffer overflow has been discovered in the GNU C     Library (aka glibc or libc6) in the
    __mempcpy_avx512_no_vzeroupper function when particular     conditions are met. An attacker could use this     vulnerability to cause a denial of service or     potentially execute code. (CVE-2018-11237)

  - 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)

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

The remote host is affected by the vulnerability described in GLSA-201804-02 (glibc: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in glibc. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly execute arbitrary code, escalate privileges,       cause a Denial of Service condition, or have other unspecified impacts.
  Workaround :

    There is no known workaround at this time.

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)
