Name of the Vulnerable Software and Affected Versions
SoftwareX versions prior to 0.33.1
Description
The issue arises when a node receives a block with a timestamp more than 15 seconds ahead of its local time, potentially leading to the block being marked as invalid and the peer being banned. To prevent network splitting by an attacker mining a block near the 15-second boundary, the software should not disconnect a peer for serving a block header that is too far ahead.
Recommendations
For versions prior to 0.33.1, upgrade to v0.33.1 or above.
As a temporary workaround, consider not banning peers that serve too-far-ahead block headers until a patch is applied.
