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 privileges 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 CAN-200 5-2876 to this issue.
This update also fixes a hardlink bug in the script command for Red Hat Enterprise Linux 2.1. If a local user places a hard linked 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 CAN-200 1-1494 to this issue.
