Mandriva Linux Security Advisory 2015-223 - 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 and possibly execute arbitrary code via the Voodoo interface, which triggers a stack-based buffer overflow. The Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB allows remote attackers to cause a denial of service and possibly execute arbitrary code via the Voodoo interface, which triggers an out-of-bounds write.

Package : directfb
Date : May 4, 2015
Affected: Business Server 1.0, Business Server 2.0
_______________________________________________________________________
Problem Description:
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).
