- →The vulnerable function is `restore_page_device` in `psi/zdevice2.c`; monitor for Ghostscript processing PS or PDF files that trigger this code path without stack-space validation. ↗
- →Attack vector includes specially-crafted PS or PDF files; also triggers via file-manager thumbnail generation — monitor thumbnail/preview processes spawning Ghostscript. ↗
- ·Red Hat Enterprise Linux 6 will NOT receive a fix; systems running RHEL 6 with Ghostscript remain permanently vulnerable unless mitigated via the CVE-2018-16509 mitigation guidance. ↗
- ·Starting from RHEL 7.6, the thumbnailer is executed in a sandbox, reducing the thumbnail-generation attack surface on that platform. ↗

CVE-2018-19409 Ghostscript vulnerabilities
Title: Ghostscript vulnerabilities
Summary: Several security issues were fixed in Ghostscript.
It was discovered that Ghostscript contained multiple security issues. If a
user or automated system were tricked into processing a specially crafted
file, a remote attacker could possibly use these issues to access arbitrary
files, execute arbitrary code, or cause a denial of service.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
