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

medium Nessus Plugin ID 60760

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.
