Debian DSA-1458-1 : openafs - programming error

medium Nessus Plugin ID 29935
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

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.

Solution

Upgrade the openafs packages.

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.
