Scientific Linux Security Update : GFS on SL3.x i386/x86_64

medium Nessus Plugin ID 60760
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 Scientific Linux host is missing one or more security updates.

Description

A flaw was found in the gfs_lock() implementation. The GFS locking code could skip the lock operation for files that have the S_ISGID bit (set-group-ID on execution) in their mode set. A local, unprivileged user on a system that has a GFS file system mounted could use this flaw to cause a kernel panic. (CVE-2010-0727)

As well, these updated GFS packages are in sync with the latest kernel (2.4.21-63.EL). The modules in earlier GFS packages fail to load because they do not match the running kernel. It is possible to force-load the modules; however, with this update, force-loading the modules is not required. (BZ#525198)

Users are advised to upgrade to these latest GFS packages, which resolve this issue and are updated for use with the 2.4.21-63.EL kernel.

Solution

Update the affected packages.
