   An update that fixes two vulnerabilities is now available.

Description:

   DirectFB was updated to fix two security issues.

   The following vulnerabilities were fixed:

   * CVE-2014-2977: Multiple integer signedness errors could allow remote
     attackers to cause a denial of service (crash) and possibly execute
     arbitrary code via the Voodoo interface, which triggers a stack-based
     buffer overflow.
   * CVE-2014-2978: Remote attackers could cause a denial of service (crash)
     and possibly execute arbitrary code via the Voodoo interface, which
     triggers an out-of-bounds write.
