Stack-based buffer overflow in the get_key function in parse.c in abcm2ps through 8.13.20 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

Security readout for executives and security teams

Plain-English summary

CVE-2018-10771 is a stack-based buffer overflow in abcm2ps through 8.13.20. A malicious input could crash the application, and the CVE leaves room for unspecified additional impact. Business urgency is highest where abcm2ps processes files from untrusted users or automated ingestion paths.

Executive priority

Prioritize remediation where abcm2ps is used in production automation or accepts files from outside the organization. For isolated desktop or trusted-only usage, schedule normal patching. The main proven impact is service disruption, while broader impact is not documented in the provided sources.

Technical view

The flaw is in get_key in parse.c. The source description identifies stack-based buffer overflow behavior, with remote attackers able to cause denial of service and possibly unspecified other impact. Public sources do not provide CVSS, CWE, confirmed code execution, or detailed affected package scope beyond abcm2ps through 8.13.20.

Likely exposure

Exposure is likely limited to systems that have abcm2ps installed and process ABC notation files or similar input from users, email, web uploads, repositories, or batch jobs. General servers are not exposed unless abcm2ps is reachable through a file-processing workflow.

Exploitation context

The bundle does not show CISA KEV listing or confirmed active exploitation. The public description states remote attackers can trigger a crash, which implies exploitation depends on getting crafted content processed by abcm2ps. Treat internet-facing or automated conversion services as higher risk.

Researcher notes

Evidence is sparse. The key facts are the vulnerable function, stack overflow class, version range through 8.13.20, and DoS impact. Fedora and Debian advisories indicate downstream security updates, but the bundle does not include CVSS, a CWE assignment, patch diff details, or proof of active exploitation.

Mitigation direction

  • Upgrade abcm2ps using vendor or distribution security updates where available.
  • Check Fedora and Debian advisories for packaged update availability.
  • Avoid processing untrusted input with vulnerable abcm2ps versions.
  • Isolate conversion workflows from sensitive services and data.
  • Monitor vendor guidance for any clarified fixed version or impact details.

Validation and detection

  • Inventory systems and containers for abcm2ps installations.
  • Confirm installed versions are newer than 8.13.20 or vendor-patched.
  • Identify workflows that pass user-controlled files into abcm2ps.
  • Review package manager security advisories for Fedora or Debian systems.
  • Check crash reports or logs around abcm2ps file-processing jobs.
