CVE-2007-1246
CWE-119Published: March 3, 2007· Updated: Jun 16, 2026
Official Description
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.
Technical Analysis
CVE-2007-1246 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
