GLSA-200504-12 : rsnapshot: Local privilege escalation

medium Nessus Plugin ID 18045

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-200504-12 (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
