application movie file buffer overflow
| application-movie-file-bo (44654) |  High Risk |
Description:
Xvid is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the decoder_iframe(), decoder_pframe(), and decoder_bframe() functions in the video compression codec. By persuading a victim to open a specially-crafted movie file containing macroblock values, a remote attacker could overflow a buffer to corrupt memory and execute arbitrary code on the system.
