|Gentoo Linux Security Advisory
Title: OpenAFS: Denial of Service (GLSA 200801-04)
Date: January 09, 2008
A Denial of Service vulnerability has been discovered in OpenAFS.
OpenAFS is a distributed network filesystem.
Vulnerable: < 1.4.6
Unaffected: >= 1.4.6
Architectures: All supported architectures
Russ Allbery, Jeffrey Altman, Dan Hyde and Thomas Mueller discovered a race condition due to an improper handling of the clients callbacks lists.
A remote attacker could construct cases which trigger the race condition, resulting in a server crash.
There is no known workaround at this time.
All OpenAFS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/openafs-1.4.6"
