Amazon Linux 2 : glibc (ALAS-2022-1869)

high Nessus Plugin ID 167239

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

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.

Solution

Run 'yum update glibc' to update your system.
