| Subject: [PATCH 3/7] Bug700317: Fix logic for an older change |
| |
| Unlike almost every other function in gs, dict_find_string() returns 1 on |
| success 0 or <0 on failure. The logic for this case was wrong. |
| |
| CVE: CVE-2019-6116 |
| Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git] |
