Ubuntu 20.04 LTS / 22.04 LTS / 23.04 : libwebp vulnerability (USN-6369-1)

high Nessus Plugin ID 181426

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by a vulnerability as referenced in the USN-6369-1 advisory.

 It was discovered that libwebp incorrectly handled certain malformed images.

 If a user or automated system were tricked into opening a specially crafted image file, a remote attacker could use this issue to cause libwebp 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.
