Name of the Vulnerable Software and Affected Versions Bitcoin Core versions prior to 22.0 Bitcoin Core versions 27.x

Description The issue is caused by an integer overflow in CAddrMan's nIdCount via a flood of addr messages, leading to an assertion failure and daemon exit. This can be exploited to cause a remote crash.

Recommendations For Bitcoin Core versions prior to 22.0, update to version 22.0 or later to resolve the issue. For Bitcoin Core versions 27.x, update to version 28.x or 29.x to resolve the issue.
