A use-after-free flaw was found in the way libXfont processed certain font files when attempting to add a new directory to the font path. A malicious, local user could exploit this issue to potentially execute arbitrary code with the privileges of the X.Org server.
(CVE-2014-0209)
Multiple out-of-bounds write flaws were found in the way libXfont parsed replies received from an X.org font server. A malicious X.org server could cause an X client to crash or, possibly, execute arbitrary code with the privileges of the X.Org server.
(CVE-2014-0210, CVE-2014-0211)
All running X.Org server instances must be restarted for the update to take effect.
