Echo: gdk-pixbuf: security update to 2.42.12+dfsg-4+e6

medium Tenable Cloud Security Plugin ID 472738

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in gdk-pixbuf. When parsing a specially crafted ICO file with pixel values that exceed
 the defined palette range, an out-of-bounds read can occur due to improper bounds checking against the
 actual palette size. This vulnerability causes heap bytes to be interpreted as valid palette indices and
 rendered as RGB pixel values in the output image, allowing an attacker to extract heap content via the
 generated output, such as a thumbnail. (CVE-2026-16768)

Solution

Update the gdk-pixbuf library and its related packages to version 2.42.12+dfsg-4+e6 or later.
