Description Victor Pereira 2015-01-29 09:30:44 UTC 
rh#1184490

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].

As far as I can see this is fixed since GNU patch version 2.7.3, presumably by commit "For renames and copies, make sure that both file names are valid":
