| Subject: [PATCH 1/2] Undefine some additional internal operators. |
| |
| .type, .writecvs, .setSMask, .currentSMask |
| |
| These don't seem to be referenced anywhere outside of the initialization code, |
| which binds their usages. Passes cluster if they are removed. |
| |
| CVE: CVE-2018-18073 |
| Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git] |
