Denial of service via HAMT Decoding Panics
概要
Denial of service via HAMT Decoding Panics
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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 bogus fanout parameter in the HAMT directory nodes.
This include 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).
Patches
Workarounds
Do not feed untrusted user data to the decoding functions.
