GLSA-200504-25 : Rootkit Hunter: Insecure temporary file creation

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200504-25
(Rootkit Hunter: Insecure temporary file creation)

Sune Kloppenborg Jeppesen and Tavis Ormandy of the Gentoo Linux
Security Team have reported that the check_update.sh script and the
main rkhunter script insecurely creates several temporary files with
predictable filenames.

Impact :

A local attacker could create symbolic links in the temporary
files directory, pointing to a valid file somewhere on the filesystem.
When rkhunter or the check_update.sh script runs, this would result in
the file being overwritten with the rights of the user running the
utility, which could be the root user.

Workaround :

There is no known workaround at this time.

Solution :

All Rootkit Hunter users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-forensics/rkhunter-1.2.3-r1'

Risk factor :

Low / CVSS Base Score : 2.1
