"X.Org and XFree86, including libX11, xdm, xf86dga, xinit, xload,
xtrans, and xterm, does not check the return values for setuid and
seteuid calls when attempting to drop privileges, which might allow
local users to gain privileges by causing those calls to fail, such as
by exceeding a ulimit.

In practice, it is unlikely that these programs have any real-world
vulnerability. The X binary is the only one shipped suid. Further
analysis of the code in question shows that it's highly unlikely that
this can be exploited. Patched updates are provided as a precaution
nonetheless.

Updated packages are patched to address this issue."
