   An update that fixes three vulnerabilities is now available.

Description:


   LibXFont was updated to fix security problems that could be used by local
   attackers to gain X server privileges (root).

   The following security issues have been fixed:

       *

         CVE-2015-1802: The bdf parser reads a count for the number of
   properties defined in a font from the font file, and allocates arrays with
   entries for each property based on that count. It never checked to see if
   that count was negative, or large enough to overflow when multiplied by
   the size of the structures being allocated, and could thus allocate the
   wrong buffer size, leading to out of bounds writes.

       *

         CVE-2015-1803: If the bdf parser failed to parse the data for the
   bitmap for any character, it would proceed with an invalid pointer to the
   bitmap data and later crash when trying to read the bitmap from that
   pointer.

       *

         CVE-2015-1804: The bdf parser read metrics values as 32-bit
   integers, but stored them into 16-bit integers. Overflows could occur in
   various operations leading to out-of-bounds memory access.

   Security Issues:

       * CVE-2015-1802
