Updated directfb packages fix security vulnerabilities

Updated directfb packages fix security vulnerabilities: Multiple integer signedness errors in the Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB 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-2014-2977). The Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers an out-of-bounds write (CVE-2014-2978).
