SCA: security update for github.com/btcsuite/btcd (GHSA-27vh-h6mc-q6g8)

high Tenable Cloud Security Plugin ID 408779

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - btcd is an alternative full node bitcoin implementation written in Go (golang). The btcd Bitcoin client
 (versions 0.10 to 0.24) did not correctly re-implement Bitcoin Core's "FindAndDelete()" functionality.
 This logic is consensus-critical: the difference in behavior with the other Bitcoin clients can lead to
 btcd clients accepting an invalid Bitcoin block (or rejecting a valid one). This consensus failure can be
 leveraged to cause a chain split (accepting an invalid Bitcoin block) or be exploited to DoS the btcd
 nodes (rejecting a valid Bitcoin block). An attacker can create a standard transaction where FindAndDelete
 doesn't return a match but removeOpCodeByData does making btcd get a different sighash, leading to a chain
 split. Importantly, this vulnerability can be exploited remotely by any Bitcoin user and does not require
 any hash power. This is because the difference in behavior can be triggered by a "standard" Bitcoin
 transaction, that is a transaction which gets relayed through the P2P network before it gets included in a
 Bitcoin block. `removeOpcodeByData(script []byte, dataToRemove []byte)` removes any data pushes from
 `script` that contain `dataToRemove`. However, `FindAndDelete` only removes exact matches. So for example,
 with `script = "<data> <data||foo>"` and `dataToRemove = "data"` btcd will remove both data pushes but
 Bitcoin Core's `FindAndDelete` only removes the first `<data>` push. This has been patched in btcd version
 v0.24.2. Users are advised to upgrade. There are no known workarounds for this issue. (CVE-2024-38365)
