Description

IRIX contains a flaw that may allow a malicious local user to overwrite arbitrary files on the system. The issue is due to the fsdump program creating files insecurely. It is possible for a user to use a symlink style attack to manipulate arbitrary files, resulting in a loss of integrity.

Classification

Attack Type: Race Condition
Impact: Loss of Integrity
Exploit: Exploit Public
Disclosure: OSVDB Verified

Solution

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Remove the setuid bit on the fsdump program or to remove the rfindd subsystem.
