Details

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.
