   An update that fixes three vulnerabilities is now available.


   LibXFont was updated to fix security problems.

   Following security issues were 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
     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

   - 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.
