Comment 1 Robert Frohl 2023-08-23 14:54:07 UTC

bsc#1175719 was fixed via version update, closing as invalid

Comment 2 Johannes Meixner 2023-09-05 11:38:07 UTC

Actually closing as invalid according to
https://bugzilla.suse.com/show_bug.cgi?id=1214536#c1

Ghostscript version 9.51 contains the fix for CVE-2020-16305
and meanwhile we have Ghostscript 9.52 in SLE12 and SLE15.

FYI:
Our Ghostscript 9.52 has also CVE-2023-38559 fixed
which is in base/gdevdevn.c the same issue
"ordering in if expression to avoid out-of-bounds access"
as the already fixed CVE-2020-16305 in devices/gdevpcx.c
see bug #1213637
