Category:	Ubuntu Local Security Checks
Title:	Ubuntu USN-550-3 (libcairo)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to libcairo announced via advisory USN-550-3. A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 6.10 Ubuntu 7.04 Ubuntu 7.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. 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. Original advisory details: 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. Solution: The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: libcairo2 1.0.4-0ubuntu1.2 Ubuntu 6.10: libcairo2 1.2.4-1ubuntu2.2 Ubuntu 7.04: libcairo2 1.4.2-0ubuntu1.3 Ubuntu 7.10: libcairo2 1.4.10-1ubuntu4.4 After a standard system upgrade you need to restart your session to effect the necessary changes. http://www.securityspace.com/smysecure/catid.html?in=USN-550-3 Risk factor : High
