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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:3942-2 advisory.

  - 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 this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:3942-1 advisory.

  - 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 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)

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

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0832-1 advisory.

  - 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)

  - A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory     corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and     size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and     escalate their privileges on the system. (CVE-2021-3999)

  - The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc)     through 2.34 copies its path argument on the stack without validating its length, which may result in a     buffer overflow, potentially resulting in a denial of service or (if an application is not built with a     stack protector enabled) arbitrary code execution. (CVE-2022-23218)

  - The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc)     through 2.34 copies its hostname argument on the stack without validating its length, which may result in     a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a     stack protector enabled) arbitrary code execution. (CVE-2022-23219)

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