Ubuntu 20.04 LTS / 22.04 LTS / 23.10 : GNU C Library vulnerability (USN-6737-1)

high Nessus Plugin ID 193515

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6737-1 advisory.

Charles Fol discovered that the GNU C Library iconv feature incorrectly handled certain input sequences.
An attacker could use this issue to cause the GNU C Library to crash, resulting in 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.
