Description Vasyl Kaigorodov 2015-01-21 14:30:18 UTC

It was reported [1] that the versions of the patch utility that support Git-style patches are vulnerable to a directory traversal flaw. This could allow an attacker to overwrite arbitrary files by applying a specially crafted patch, with the privileges of the user running patch. A reproducer for this issue is available in [1].

Comment 4 Vincent Danen 2015-07-31 04:43:08 UTC

This is really only problematic if you're a) running patch on patch files you've not inspected first or b) are running patch as root.  In either case, you shouldn't be patching things as root unless they're trusted and possibly it's worth inspecting patch files first.
