Description Robert Frohl 2018-11-26 13:41:37 UTC
CVE-2018-19475

psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to
bypass intended access restrictions because available stack space is not checked
when the device remains the same.

Hi Johannes,
my investigation suggests that all codestreams are affected:
- SUSE:SLE-15:Update/ghostscript
- SUSE:SLE-12:Update/ghostscript

The following are rated as affected because of a dependency on backports for CVE-2018-16802(bsc#1108027):
- SUSE:SLE-11-SP1:Update/ghostscript-library
- SUSE:SLE-10-SP3:Update/ghostscript-library
