CVE-2014-2978: Buffer Overflow
First published: Wed Jun 11 2014(Updated: )
The Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB 1.4.4 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.
