high Nessus Plugin ID 29696
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
USN-550-1 fixed vulnerabilities in Cairo. A bug in font glyph rendering was uncovered as a result of the new memory allocation routines. In certain situations, fonts containing characters with no width or height would not render any more. This update fixes the problem.We apologize for the inconvenience.
Peter Valchev discovered that Cairo did not correctly decode PNG image data. By tricking a user or automated system into processing a specially crafted PNG with Cairo, a remote attacker could execute arbitrary code with user privileges.
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.
