MTR MTR_OPTIONS environment variable buffer overflow
|mtr-options-bo (8367)||High Risk|
MTR is vulnerable to a buffer overflow caused by improper bounds checking of the MTR_OPTIONS environment variable. By supplying an overly long specially-crafted string to MTR_OPTIONS, a local attacker could overflow a buffer and execute arbitrary code on the system with root privileges.
Upgrade to the latest version of MTR (0.49 or later), available from the BitWizard FTP site. See References.
For Debian GNU/Linux 2.2 (potato):
Upgrade to the latest version of mtr (0.41-6 or later), as listed in DSA-124-1. See References.
