The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2722-1 advisory.
Gustavo Grieco discovered that GDK-PixBuf incorrectly handled scaling bitmap images. If a user or automated system were tricked into opening a BMP image file, a remote attacker could use this flaw to cause GDK-PixBuf 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.
