CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2017-8291 is a high-severity Type Confusion (CWE-843) vulnerability in Redhat Enterprise Linux Eus. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Artifex Ghostscript through 2017-04-26 is affected by a type confusion vulnerability (CWE-843) involving the .rsdparams parameter. When a crafted .eps file containing an "/OutputFile (%pipe%" substring is processed by the gs program, the flaw permits a bypass of the -dSAFER sandbox and enables arbitrary command execution.
An attacker can supply the malicious EPS document as input to Ghostscript, achieving remote command execution on the target system. The attack requires local access or user interaction to open the file and carries a CVSS 7.8 rating reflecting high impact on confidentiality, integrity, and availability.
The issue was exploited in the wild in April 2017. Security advisories and updates addressing the flaw were issued by distributions including Debian (DSA-3838) and Red Hat (RHSA-2017:1230), along with a Ghostscript bug tracker entry.
