VLC Media Player memmove() function buffer overflow
| vlcmediaplayer-memmove-bo (44659) |  High Risk |
Description:
VLC Media Player is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the memmove() function in mmstu.c. By persuading a victim to open a specially-crafted Microsoft Media Services Stream (MMS), a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
