Ubuntu 22.04 LTS / 24.04 LTS / 25.04 : GNU C Library vulnerability (USN-7760-1)

medium Nessus Plugin ID 265732

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by a vulnerability as referenced in the USN-7760-1 advisory.

 It was discovered that the GNU C Library incorrectly handled the regcomp function when memory allocation failures occured. An attacker could use this issue to cause applications to crash, leading to a denial of service, or possibly execute arbitrary code.

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

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

Solution

Update the affected packages.
