MPlayer DMO_VideoDecoder() buffer overflow
| mplayer-dmovideodecoder-bo (32747) |  High Risk |
Description:
MPlayer is vulnerable to a buffer overflow, caused by improper bounds checking by the DMO_VideoDecoder function. By creating a specially-crafted video file with an overly long biSize value, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash, if the attacker could persuade the victim to open the malicious video file.

- CVE-2007-1246: 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.
