CVE-2007-1246

Estado: ModificadaAlta (7.6)—
The DMO_VideoDecoder_Open function in loader/dmo/DMO_VideoDecoder.c in MPlayer 1.0rc1 and earlier, as used in xine-lib, does not set the biSize before use in a memcpy, which allows user-assisted remote attackers to cause a buffer overflow and possibly execute arbitrary code, a different vulnerability than CVE-2007-1387.
