"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)"
