Which packages are affected by GHSA-3gjh-29fv-8hr6?

GHSA-3gjh-29fv-8hr6 affects the following packages: ckb (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-3gjh-29fv-8hr6?

Update ckb to 0.34.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3gjh-29fv-8hr6 is resolved across your whole dependency graph.

How do I detect GHSA-3gjh-29fv-8hr6 in my crates.io dependencies?

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

How do I mitigate GHSA-3gjh-29fv-8hr6 if there is no patch (or I can't update yet)?

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.

Is GHSA-3gjh-29fv-8hr6 actively exploited in the wild?

No public exploit code has been indexed for GHSA-3gjh-29fv-8hr6 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-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

Impact

Adversary can create message which compressed size is less than the package limit but the decompressed length is very large such as 1G. It will cost the node many memories to process the network messages, and on the system with less than 1G memory, the process is killed directly because of out of memory error.

Patches

The node must check the decompress length before allocating the memory for the message.
