The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6806-1 advisory.
Pedro Ribeiro and Vitor Pedreira discovered that the GDK-PixBuf library did not properly handle certain ANI files. An attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or to 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.
