+Subject: [PATCH] Undef /odef in gs_init.ps
+
+Made a new temporary utility function in gs_cet.ps (.odef) to use instead
+of /odef. This makes it fine to undef odef with all the other operators in
+gs_init.ps
+
+This punts the bigger question of what to do with .makeoperator, but it
+doesn't make the situation any worse than it already was.
+
+CVE: CVE-2019-3835
+Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git]
