"Alan Coopersmith reports :

Ilja van Sprundel, a security researcher with IOActive, has discovered
several issues in the way the libXfont library handles the responses
it receives from xfs servers, and has worked with X.Org's security
team to analyze, confirm, and fix these issues.

Most of these issues stem from libXfont trusting the font server to
send valid protocol data, and not verifying that the values will not
overflow or cause other damage. This code is commonly called from the
X server when an X Font Server is active in the font path, so may be
running in a setuid-root process depending on the X server in use.
Exploits of this path could be used by a local, authenticated user to
attempt to raise privileges; or by a remote attacker who can control
the font server to attempt to execute code with the privileges of the
X server."
