GHSA-gw5w-5j7f-jmjj
Unsound usages of `std::slice::from_raw_parts`
Blast Radius
pprofReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
The library breaks the safety assumptions when using unsafe API std::slice::from_raw_parts. First, when using the API in iterator implementation (TempFdArrayIterator.next), generic type could be any type, which would create and pass a misaligned pointer to the unsafe API. Second, when validating the address, the code passed the type c_void, which could also be any type, leading to potential uninitialized memory exposure.
Two unsound usages here highlight the necessity for developers to perform type checks before doing type conversion with unsafe API.
The panic caused by the misalignment causes several downstream applications (e.g., greptimedb) to crash when using pprof::report::ReportBuilder::build.
This was patched in 0.14.0.
The developer also suggested moving to pprof2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pprof. 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 pprof to 0.14.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gw5w-5j7f-jmjj 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-gw5w-5j7f-jmjj 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-gw5w-5j7f-jmjj. 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-gw5w-5j7f-jmjj in your dependencies?
O3 detects GHSA-gw5w-5j7f-jmjj across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
