   An update that fixes three vulnerabilities is now available.

Description:

   libXFont was updated to fix three vulnerabilities when parsing BDF files
   (bnc#921978)

   As libXfont is used by the X server to read font files, and an
   unprivileged user with access to the X server can tell the X server to
   read a given font file from a path of their choosing, these
   vulnerabilities have the potential to allow unprivileged users to run code
   with the privileges of the X server.

   The following vulnerabilities were fixed:
   * The BDF parser could allocate the a wrong buffer size, leading to out of
     bound writes (CVE-2015-1802)
   * The BDF parser could crash when trying to read an invalid pointer
     (CVE-2015-1803)
   * The BDF parser could read 32 bit metrics values into 16 bit integers,
     causing an out-of-bound memory access though integer overflow
     (CVE-2015-1804)
