TITLE:
OpenAFS Spoofed "FetchStatus" Privilege Escalation

SECUNIA ADVISORY ID:
SA24582

VERIFY ADVISORY:
http://secunia.com/advisories/24582/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
>From local network

SOFTWARE:
OpenAFS 1.x
http://secunia.com/product/3151/

DESCRIPTION:
A vulnerability has been reported in OpenAFS, which can be exploited
by malicious users to gain escalated privileges.

The vulnerability is caused due to AFS cache managers not using
authenticated connections for non-user-authenticated sessions. This
can be exploited to gain escalated privileges by flushing the local
cache and spoofing a "FetchStatus" reply with an executable setuid
root and then running it.

Successful exploitation requires that setuid status for the local
cell is enabled.

SOLUTION:
Update to version 1.4.4 or 1.5.17.

PROVIDED AND/OR DISCOVERED BY:
Benjamin Bennett, Pittsburgh Supercomputing Center.
