mhc-utils adb2mhc creates an insecure temporary directory
|mhc-adb2mhc-insecure-tmp (11439)||Medium Risk|
The adb2mhc utility in the mhc-utils (Message Harmonized Calendaring system utilities) package included with Debian Linux creates a temporary directory with an easily guessable name. This could allow a local attacker to overwrite arbitrary files on the system with privileges of the adb2mhc process owner.
For Debian GNU/Linux 3.0 (woody):
Upgrade to the latest mhc-utils package (0.25+20010625-7.1 or later), as listed in DSA 256-1. See References.
