Background ========== rsnapshot is a filesystem snapshot utility based on rsync, allowing local and remote systems backups. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/rsnapshot < 1.2.1 >= 1.2.1 Description =========== 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. Resolution ========== All rsnapshot users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/rsnapshot-1.2.1" References ========== [ 1 ] rsnapshot Security Advisory 001 http://www.rsnapshot.org/security/2005/001.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200504-12.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
