  script_tag(name:"insight", value:"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)");
