Scientific Linux Security Update : fuse on SL6.x i386/x86_64
Medium Nessus Plugin ID 61086
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionFUSE (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)
All users should upgrade to these updated packages, which contain backported patches to correct these issues.
