  script_tag(name:"insight", value:"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

  * CVE-2015-1803

  * CVE-2015-1804");
