Description

Ilja van Sprundel discovered multiple security issues in various X.org libraries and components. An attacker could use these issues to cause applications 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.
