Insight
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.
