X.Org Security Advisory: October 8, 2013 - CVE-2013-4396
Use after free in Xserver handling of ImageText requests
Description:
Pedro Ribeiro (pedrib at gmail.com) reported an issue to the X.Org
security
team in which an authenticated X client can cause an X server to use
memory
after it was freed, potentially leading to crash and/or memory
corruption.
Affected Versions =
This bug appears to have been introduced in RCS version 1.42 on
1993/09/18,
and is thus believed to be present in every X server release starting
with
X11R6.0 up to the current xorg-server 1.14.3. (Manual inspection shows
it
is present in the sources from the X11R6 tarballs, but not in those from
the
X11R5 tarballs.)
Fixes =
A fix is available via the attached patch, which is intended to be
included
in xorg-server 1.15.0 and 1.14.4.
