It was reported 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. GNU patch before 2.7.4 allows remote attackers to write to arbitrary files via a symlink attack in a patch file.
