The remote NewStart CGSL host, running version MAIN 6.06, has glibc packages installed that are affected by multiple vulnerabilities:

  - The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It     may use the notification thread attributes object (passed through its struct sigevent parameter) after it     has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified     other impact. (CVE-2021-33574)

  - 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)

  - The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple     suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite     loop when processing invalid multi-byte input sequences, leading to a denial of service. (CVE-2016-10228)

  - The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to     cause a denial of service (out-of-bounds read and crash) via 64 bytes of input. (CVE-2016-6261)

  - The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent     attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.
    (CVE-2016-6263)

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

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)

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)

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)

This update for glibc fixes the following issues :

  - A privilege escalation bug in the realpath() function     has been fixed. [CVE-2018-1000001, bsc#1074293]

  - A memory leak and a buffer overflow in the dynamic ELF     loader has been fixed. [CVE-2017-1000408,     CVE-2017-1000409, bsc#1071319]

  - An issue in the code handling RPATHs was fixed that     could have been exploited by an attacker to execute code     loaded from arbitrary libraries. [CVE-2017-16997,     bsc#1073231]

  - A potential crash caused by a use-after-free bug in     pthread_create() has been fixed. [bsc#1053188]

  - A bug that prevented users to build shared objects which     use the optimized libmvec.so API has been fixed.
    [bsc#1070905]

  - A memory leak in the glob() function has been fixed.
    [CVE-2017-15670, CVE-2017-15671, CVE-2017-15804,     bsc#1064569, bsc#1064580, bsc#1064583]

  - A bug that would lose the syscall error code value in     case of crashes has been fixed. [bsc#1063675]

This update addresses two security vulnerabilities :

  - CVE-2017-15670, CVE-2017-15671, CVE-2017-15804: Various     vulnerabilities could lead to memory corruption in the     `glob` and `glob64` function. (RHBZ#1505298,     RHBZ##1504807)

  - CVE-2017-16997: Check for empty tokens before dynamic     string token expansion in the dynamic linker, so that     pre-existing privileged programs with `$ORIGIN`     rpaths/runpaths do not cause the dynamic linker to     search the current directory, potentially leading to     privilege escalation. (RHBZ#1526866).

  - CVE-2018-1000001: `getcwd` would sometimes return a     non-absolute path, confusing the `realpath` function,     leading to privilege escalation in conjunction with user     namespaces. (RHBZ#1533837) 

In addition, this update replaces the dynamic linker trampoline on x86-64 with a version which uses the `XSAVE` instruction if it is available. This improves compatibility with future hardware and compilers which do not follow the x86-64 ABI. This update also adjusts the thread stack size accounting to provide additional stack space compared to previous glibc versions (to avoid introducing RHBZ#1527887).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.

Security Fix(es) :

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can     be used to execute code loaded from arbitrary libraries     (CVE-2017-16997)

  - glibc: Integer overflow in posix_memalign in memalign     functions (CVE-2018-6485)

  - glibc: Integer overflow in stdlib/canonicalize.c on     32-bit architectures leading to stack-based buffer     overflow (CVE-2018-11236)

  - glibc: Buffer overflow in __mempcpy_avx512_no_vzeroupper     (CVE-2018-11237)

An update for glibc is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary libraries (CVE-2017-16997)

* glibc: Integer overflow in posix_memalign in memalign functions (CVE-2018-6485)

* glibc: Integer overflow in stdlib/canonicalize.c on 32-bit architectures leading to stack-based buffer overflow (CVE-2018-11236)

* glibc: Buffer overflow in __mempcpy_avx512_no_vzeroupper (CVE-2018-11237)

    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.

An update of the glibc package has been released.

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)

  - 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.

According to the versions of the glibc packages installed, the EulerOS Virtualization for ARM 64 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 AVX-512-optimized implementation of the mempcpy     function in the GNU C Library (aka glibc or libc6) 2.27     and earlier may write data beyond the target buffer,     leading to a buffer overflow in
    __mempcpy_avx512_no_vzeroupper.(CVE-2018-11237)

  - 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.

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 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)

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