The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4954-1 advisory.

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

  - An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc     2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative     value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the     'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-     of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows     for program execution to continue in scenarios where a segmentation fault or crash should have occurred.
    The dangers occur in that subsequent execution and iterations of this code will be executed with this     corrupted data. (CVE-2020-6096)

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

This update for glibc fixes the following issues :

Security issues fixed :

CVE-2019-9169: regex: fix read overrun (bsc#1127308, BZ #24114)

Non-security issues fixed: Enable TLE only if GLIBC_ELISION_ENABLE=yes is defined (bsc#1131994, fate#322271)

Add more checks for valid ld.so.cache file (bsc#1110661, BZ #18093)

Added cfi information for start routines in order to stop unwinding (bsc#1128574)

ja_JP locale: Add entry for the new Japanese era (bsc#1100396, fate#325570, BZ #22964)

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.

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K64119434 advisory.

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

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

The version of glibc installed on the remote host is prior to 2.26-62. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1869 advisory.

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

  - The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent attackers     to cause a denial of service (assertion failure and application crash) via vectors related to extended     regular expression processing. (CVE-2015-8985)

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

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

  - In the GNU C Library (aka glibc or libc6) before 2.28,     parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial     of service (assertion failure and application exit) or     trigger an incorrect result by attempting a     regular-expression match.(CVE-2009-5155)

  - In the GNU C Library (aka glibc or libc6) through 2.29,     proceed_next_node in posix/regexec.c has a heap-based     buffer over-read via an attempted case-insensitive     regular-expression match.(CVE-2019-9169)

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.
