Advisory 2007-06-01.01

Outpost Enforcing system reboot with 'outpost_ipc_hdr' mutex Vulnerability

Basic information:


Release date: June 01, 2007

Last update: November 02, 2007

Severity:Low

Character:Denial of service

Status:Fixed

Testing program: BTP00002P004AO.zip

Description:

Outpost insufficiently protects its own mutex outpost_ipc_hdr. Arbitrary process is able to open and capture this mutex. In such case, Outpost is not able to use this mutex for its synchronization and its internal mechanisms lock when they try to use it. Outpost uses this mutex every time a potentially dangerous operation is executed. For example, this results in an impossibility of running new processes while the mutex is locked. After the mutex is released, all blocked operations completes. However, the release can not be enforced. Users are thus forced to reboot the system.
