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)
