Midnight Commander vfs_s_resolve_symlink buffer overflow
| midnight-commander-vfssresolvesymlink-bo (13247) |  High Risk |
Description:
Midnight Commander (mc) is vulnerable to a stack-based buffer overflow, caused by a vulnerability in the vfs_s_resolve_symlink function. By creating a specially-crafted archive file, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the Midnight Commander user, once the victim opens the file.
