Description Vincent Danen 2011-09-23 21:55:06 UTC

It was reported [1] that ProcRenderAddGlyphs() suffered from an input sanitization flaw.  This could allow a local attacker to possibly expose arbitrary memory or crash the X server.

This has been fixed upstream [2].

Comment 1 Vincent Danen 2011-09-23 22:02:09 UTC

This doesn't affect Fedora 14+ (xorg-server-1.9.5) as the patch in [2] is applied.
