CVE-2023-43115
A public proof of concept exists; no exploitation attested.
- Published2023-09-18
Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
In Artifex Ghostscript through 10.01.2, gdevijs.c in GhostPDL can lead to remote code execution via crafted PostScript documents because they can switch to the IJS device, or change the IjsServer parameter, after SAFER has been activated. NOTE: it is a documented risk that the IJS server can be specified on a gs command line (the IJS device inherently must execute a command to start the IJS server).
