EulerOS 2.0 SP3 : compat-glibc (EulerOS-SA-2022-1158)

critical Nessus Plugin ID 158300

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations. (CVE-2021-35942)

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.

Solution

Update the affected compat-glibc packages.
