Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io, PyPI packages — download data is not available via public APIs for these ecosystems.

Description

A security flaw has been discovered in lief-project LIEF up to 0.17.1. Affected by this issue is the function Parser::parse_binary of the file src/ELF/Parser.tcc of the component ELF Binary Parser. The manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.17.2 can resolve this issue. The patch is identified as 81bd5d7ea0c390563f1c4c017c9019d154802978. It is recommended to upgrade the affected component.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update lief to 0.17.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mjjp-xjfg-97wg is resolved across your whole dependency graph.

  3. Workarounds

    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.
