Description

Tomas Hoger discovered that the CUPS image library incorrectly handled LZW streams. A remote attacker could use this flaw to cause 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.
