+ <background>
+ <p>
+ LibXfont is the X.Org font library. TightVNC is a VNC client/server for
+ X displays.
+ </p>
+ </background>
+ <description>
+ <p>
+ The libXfont code is prone to several integer overflows, in functions
+ ProcXCMiscGetXIDList(), bdfReadCharacters() and FontFileInitTable().
+ TightVNC contains a local copy of this code and is also affected.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ A local attacker could use a specially crafted BDF Font to gain root
+ privileges on the vulnerable host.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </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-1.2.7-r1"</code>
+ <p>
+ All TightVNC users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-misc/tightvnc-1.2.9-r4"</code>
