GHSA-p33r-fqw2-rqmm is a medium-severity (CVSS 5.3) NULL Pointer Dereference vulnerability in Magick.NET-Q16-AnyCPU. O3 Security confirms whether GHSA-p33r-fqw2-rqmm is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
In ReadSFWImage() (coders/sfw.c), when temporary file creation fails, read_info is destroyed before its filename member is accessed, causing a NULL pointer dereference and crash.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Magick.NET-Q16-AnyCPU. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update Magick.NET-Q16-AnyCPU to 14.10.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p33r-fqw2-rqmm is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-p33r-fqw2-rqmm is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-p33r-fqw2-rqmm. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-p33r-fqw2-rqmm in your dependencies?
O3 detects GHSA-p33r-fqw2-rqmm across NuGet dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
