How to Fix CVE-2023-23631

To remediate this vulnerability, upgrade all affected Github.com/ipfs/go unixfsnode dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/ipfs/go-unixfsnode fixed: 1.5.2 
Upgrade github.com/ipfs/go-unixfsnode to 1.5.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/ipfs/go-unixfsnode

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-23631, inspect your project dependencies for Github.com/ipfs/go unixfsnode:

inspect dependencies for github.com/ipfs/go-unixfsnode

Analyze the terminal output to locate any version of Github.com/ipfs/go unixfsnode in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Github.com/ipfs/go unixfsnode, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Impact Trying to read malformed HAMT sharded directories can cause panics and virtual memory leaks. If you are reading untrusted user input, an attacker can then trigger a panic. This is caused by a bogus fanout parameter in the HAMT directory nodes. This includes checks returned in [ipfs/go-bitfield GHSA-2h6c-j3gf-xp9r](https://github.com/ipfs/go-bitfield/security/advisories/GHSA-2h6c-j3gf-xp9r), as well as limiting the fanout to <= 1024 (to avoid attempts of arbitrary sized allocations). ## Patches - https://github.com/ipfs/go-unixfsnode/commit/91b3d39d33ef0cd2aff2c95d50b2329350944b68 - https://github.com/ipfs/go-unixfsnode/commit/a4ed723727e0bdc2277158337c2fc0d82802d122 ## References * https://github.com/ipfs/go-unixfs/security/advisories/GHSA-q264-w97q-q778 * https://github.com/ipfs/go-bitfield/security/advisories/GHSA-2h6c-j3gf-xp9r
