GHSA-4gj3-6r43-3wfcHighCVSS 7.5
IPFS go-unixfsnode subject to DOS via HAMT Decoding Panics
🔗 CVE IDs covered (1)
📋 Description
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, as well as limiting the fanout to <= 1024 (to avoid attempts of arbitrary sized allocations).
