Vulnerability Assessment Details

[GLSA-200504-12] rsnapshot: Local privilege escalation

Vulnerability Assessment Summary
rsnapshot: Local privilege escalation

Detailed Explanation for this Vulnerability Assessment
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.
