New Debian patch 2.7.5-1+deb9u2 fixes:
This update addresses the following issues:
* the following of symlinks in inp.c and util.c is mishandled in cases other  than input files (CVE-2019-13636)
* 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. The ed editor does not need to be  present on the vulnerable system. This is different from CVE-2018-1000156.  (CVE-2019-13638)
