EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
extractorReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Multiple heap-based buffer overflows in Libextractor 0.5.13 and earlier allow remote attackers to execute arbitrary code via (1) the asf_read_header function in the ASF plugin (plugins/asfextractor.c), and (2) the parse_trak_atom function in the QT plugin (plugins/qtextractor.c).

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for extractor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of extractor has shipped for CVE-2006-2458 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2006-2458 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2006-2458. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2006-2458 in your dependencies?
O3 Security finds CVE-2006-2458 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
