Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
