Updated patch package fixes security vulnerabilities: * In GNU patch through 2.7.6, the following of symlinks is mishandled in certain cases other than input files. (CVE-2019-13636). * A vulnerability was found in GNU patch through 2.7.6 is vulnerable to OS shell command injection that can be exploited by opening a crafted patch file that contains an ed style diff payload with shell metacharacters (CVE-2019-13638). * A vulnerability was found in do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character.
