Noroxi assessment
Priority: Now (action score 90/100)
- CISA has confirmed exploitation in the wild (May 24, 2022). Remediation deadline for US federal agencies: Jun 14, 2022.
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 96.9% (FIRST EPSS); higher than 99.8% of all records.
- Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: ghostscript (Alpine:v3.10) 9.21-r2; ghostscript (Alpine:v3.2) 9.21-r0; ghostscript (Debian:12) 9.20~dfsg-3.1.
Patch today or shut off access. Upgrade to ghostscript (Alpine:v3.10) 9.21-r2; ghostscript (Alpine:v3.2) 9.21-r0; ghostscript (Debian:12) 9.20~dfsg-3.1 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS
Artifex Ghostscript through 2017-04-26 allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile (%pipe%" substring in a crafted .eps document that is an input to the gs program, as exploited in the wild in April 2017.
