RHSA-2014:1870 -- libXfont security update (Important)

oval:org.mitre.oval:def:28435

The libXfont packages provide the X.Org libXfont runtime library. X.Org is an open source implementation of the X Window System. 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) Red Hat would like to thank the X.org project for reporting these issues. Upstream acknowledges Ilja van Sprundel as the original reporter. Users of libXfont should upgrade to these updated packages which contain a backported patch to resolve this issue. All running X.Org server instances must be restarted for the update to take effect.
