Fedora Core 2 2004-108: utempter |
||
Check for the version of the utempter package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory FEDORA-2004-108 (utempter). Utempter is a utility which permits some non-privileged programs to have required root access without compromising system security. Utempter accomplishes this feat by acting as a buffer between root and the programs. Update Information: Topic: An updated utempter package that fixes a potential symlink vulnerability is now available. Problem Description: Utempter is a utility that permits terminal applications such as xterm and screen to update utmp and wtmp without requiring root rights. Steve Grubb discovered a flaw in Utempter which permited device names containing directory traversal sequences such as '/../'. In combination with an application that trusts the utmp or wtmp files, this could permit a local attacker the ability to overwrite privileged files using a symlink. Users should upgrade to this new version of utempter, which fixes this vulnerability.
