Detailed Explanation for this Vulnerability Assessment
Updated util-linux and mount packages that fix two security issues are now
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
The util-linux package contains a large variety of low-level system
utilities that are necessary for a Linux system to function.
The mount package contains the mount, umount, swapon and swapoff programs.
A bug was found in the way the umount command is executed by normal users.
It may be possible for a user to gain elevated rights if the user is
able to execute the "umount -r" command on a mounted file system. The
file system will be re-mounted only with the "readonly" flag set, clearing
flags such as "nosuid" and "noexec". The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-2876 to
This update also fixes a hardlink bug in the script command for Red Hat
Enterprise Linux 2.1. If a local user places a hardlinked file named
"typescript" in a directory they have write access to, the file will be
overwritten if the user running script has write permissions to the
destination file. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2001-1494 to this issue.
All users of util-linux and mount should upgrade to these updated packages,
which contain backported patches to correct these issues.
