CVE intelligence and bounded remediation

CVE-2022-39381 — Muhammara is a node module with c/cpp bindings to modify PDF with js for node or electron (based/replacement on/of galkhana/hummusjs)

High CVSS 7.5

Muhammara is a node module with c/cpp bindings to modify PDF with js for node or electron (based/replacement on/of galkhana/hummusjs). The package muhammara before 2.6.0; all versions of package hummus are vulnerable to Denial of Service (DoS) when supplied with a maliciously crafted PDF file to be appended to another. This issue has been patched in 2.6.0 for muhammara and not at all for hummus. As a workaround, do not process files from untrusted sources.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
