Description

Impact

A denial-of-service was found in Exiv2 version v0.28.5: a quadratic algorithm in the ICC profile parsing code in jpegBase::readMetadata() can cause Exiv2 to run for a long time. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file.

Patches

The bug is fixed in version v0.28.6.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for exiv2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    No patched version of exiv2 has shipped for GHSA-m54q-mm9w-fp6g yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-m54q-mm9w-fp6g can be triaged on real exposure rather than presence alone.

Tailored to GHSA-m54q-mm9w-fp6g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
