Description

Ilja van Sprundel of IOActive discovered several security issues in multiple components of the X.org graphics stack and the related libraries: Various integer overflows, sign handling errors in integer conversions, buffer overflows, memory corruption and missing input sanitising may lead to privilege escalation or denial of service.
