As far as I can see this is fixed since GNU patch version 2.7.3, presumably by this commit:

For renames and copies, make sure that both file names are validhttp://git.savannah.gnu.org/cgit/patch.git/commit/?id=17953b5893f7c9835f0dd2a704ba04e0371d2cbd

So I think this bug can be closed as fixed?

Oops, sorry. I can't fix the commit message anymore now.

There's a typo in the CVE number for the last directory traversal. It's CVE-2015-1196 (missing the 6 digit on the end).

The fix for that doesn't prevent the following:
$ ls /tmp/moo
/bin/ls: cannot access /tmp/moo: No such file or directory

$ mkdir empty && cd empty

$ patch -p1 < traversal2.diff
patching file moo
patching file ../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../tmp/moo (renamed from moo)

$ ls /tmp/moo
/tmp/moo
