RHEL 2.1 : sharutils (RHSA-2003:180)

High Nessus Plugin ID 12398


The remote Red Hat host is missing a security update.


Updated packages for sharutils which fix potential privilege escalation using the uudecode utility are available.

The sharutils package contains a set of tools for encoding and decoding packages of files in binary or text format.

The uudecode utility creates an output file without checking to see if it was about to write to a symlink or a pipe. If a user uses uudecode to extract data into open shared directories, such as /tmp, this vulnerability could be used by a local attacker to overwrite files or lead to privilege escalation.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2002-0178 to this issue.

Users are advised to upgrade to these errata sharutils packages which contain a version of uudecode that has been patched to check for an existing pipe or symlink output file.


Update the affected sharutils package.
