medium Nessus Plugin ID 68309

Language:

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

From Red Hat Security Advisory 2011:1083 :

Updated fuse packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

FUSE (Filesystem in Userspace) can implement a fully functional file system in a user-space program. These packages provide the mount utility, fusermount, the tool used to mount FUSE file systems.

Multiple flaws were found in the way fusermount handled the mounting and unmounting of directories when symbolic links were present. A local user in the fuse group could use these flaws to unmount file systems, which they would otherwise not be able to unmount and that were not mounted using FUSE, via a symbolic link attack.
(CVE-2010-3879, CVE-2011-0541, CVE-2011-0542, CVE-2011-0543)

Note: The util-linux-ng RHBA-2011:0699 update must also be installed to fully correct the above flaws.

All users should upgrade to these updated packages, which contain backported patches to correct these issues.

Solution

Update the affected fuse packages.
