Detail

Synopsis

A Denial of Service vulnerability has been discovered in OpenAFS.

Background

OpenAFS is a distributed network filesystem.

Description

Russ Allbery, Jeffrey Altman, Dan Hyde and Thomas Mueller discovered a race condition due to an improper handling of the clients callbacks lists.

Impact

A remote attacker could construct cases which trigger the race condition, resulting in a server crash.

Workaround

There is no known workaround at this time.

Resolution

All OpenAFS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/openafs-1.4.6"

Title: DSA-1458-1 openafs
Description: A race condition in the OpenAFS fileserver allows remote attackers to cause a denial of service (daemon crash) by simultaneously acquiring and giving back file callbacks, which causes the handler for the GiveUpAllCallBacks RPC to perform linked-list operations without the host_glock lock.

Description: A race condition in the OpenAFS fileserver allows remote attackers to cause a denial of service (daemon crash) by simultaneously acquiring and giving back file callbacks, which causes the handler for the GiveUpAllCallBacks RPC to perform linked-list operations without the host_glock lock. For the old stable distribution (sarge), this problem has been fixed in version 1.3.81-3sarge3. For the stable distribution (etch), this problem has been fixed in version 1.4.2-6etch1. We recommend that you upgrade your openafs packages.
