+ <title>LibXfont, monolithic X.org: Multiple integer overflows</title>
+ <synopsis>
+ Some buffer overflows were discovered in the CID font parser, potentially

+ <background>
+ <p>
+ libXfont is the X.Org Xfont library, some parts are based on the
+ FreeType code base.
+ </p>
+ </background>
+ <description>
+ <p>
+ Several integer overflows have been found in the CID font parser.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ A remote attacker could exploit this vulnerability by enticing a user
+ to load a malicious font file resulting in the execution of arbitrary
+ code with the permissions of the user running the X server which
+ typically is the root user. A local user could exploit this
+ vulnerability to gain elevated privileges.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ Disable CID-encoded Type 1 fonts by removing the "type1" module and
+ replacing it with the "freetype" module in xorg.conf.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All libXfont users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=x11-libs/libXfont-1.2.1"</code>
+ <p>
+ All monolithic X.org users are advised to migrate to modular X.org.
+ </p>
