This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200504-12
(rsnapshot: Local privilege escalation)

The copy_symlink() subroutine in rsnapshot follows symlinks when
changing file ownership, instead of changing the ownership of the
symlink itself.

Impact :

Under certain circumstances, local attackers can exploit this
vulnerability to take ownership of arbitrary files, resulting in local
privilege escalation.

Workaround :

The copy_symlink() subroutine is not called if the cmd_cp parameter has
been enabled.

Solution :

All rsnapshot users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose app-backup/rsnapshot

Risk factor :
