These xorg-x11 packages also provide theX.Org libXfont runtime library.A buffer overflow flaw was found in the way the libXfont library, used bythe X.Org server, handled malformed font files compressed using UNIXcompress. A malicious, local user could exploit this issue to potentiallyexecute arbitrary code with the privileges of the X.Org server.(CVE-2011-2895)Users of xorg-x11 should upgrade to these updated packages, which containa backported patch to resolve this issue.
