Enhanced CTorrent and DTorrent btFiles::BuildFromMI() buffer overflow
| ctorrent-btfiles-bo (49959) |  High Risk |
Description:
Enhanced CTorrent and DTorrent are vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the btFiles::BuildFromMI() function. By persuading a victim to open a specially-crafted torrent file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
