FreeBSD : rkhunter -- insecure temporary file creation (f14ad681-5b88-11dc-812d-0011098b2f36)

This script is Copyright (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Gentoo reports :

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.

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.
