Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/ghostscript.
  2. 2Review the reported fix. Source-reported workaround: To mitigate this issue, avoid processing untrusted documents or standalone TrueType fonts with Ghostscript. If feasible, disable TrueType instruction execution within Ghostscript configurations. Consult Ghostscript documentation for specific configuration options to disable TrueType instruction execution. Running Ghostscript in a restrictive sandbox environment can also reduce the blast radius of potential exploitation.

Sources and claim methodology

  • Source referencebugzilla.redhat.com
Upstream source description

A flaw was found in Ghostscript. When processing a specially crafted TrueType font or document embedding one, an accounting error during font rendering can bypass buffer size checks, triggering a heap-based buffer overflow. A remote attacker could exploit this by enticing a victim or automated service to open the malicious content, potentially resulting in a Denial of Service (DoS) crash or arbitrary code execution.
