xine-lib DVD subpicture decoder buffer overflow
| xine-dvd-subpicture-bo (17423) |  High Risk |
Description:
xine is vulnerable to a heap-based buffer overflow, caused by improper bounds checking of user-supplied input in the DVD subpicture decoder. By sending a specially-crafted MPEG file with a subpicture and overlapping fields, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the user, once the file is processed by xine-lib.
