Important Security Updates
This release contains fixes for the following security vulnerabilities:
- CVE-2024-35202,
which allows remote attackers to cause a denial of service (blocktxn message-handling assertion and node exit)
by including transactions in a blocktxn message that are not committed to in a block's merkle root.
FillBlock can be called twice for one PartiallyDownloadedBlock instance.
- 5d4a2e5: backported from Bitcoin Core (a8897f6)
- Hindered block propagation due to mutated blocks,
where a peer could send mutated blocks which could clear the download state of other peers that also announced block, hindering block propagation.
- dab3bb7: backported from Bitcoin Core (dbfc748)
- Infinite loop bug in miniupnp dependency,
which could be exploited by an attacker on the local network to trigger an OOM.
- 16ba8b8: backported from Bitcoin Core (fa2a5b8)
Bug fixes
- 0d04e75: default -peerblockfilters and -blockfilterindex to off when pruning is enabled
Test related fixes
- 7d9fea0: fix functional tests that were broken by changes in 0.21.3
