Severity:	normal
Title:	Bitcoin: Denial of Service
Date:	08/07/2024
Bugs:	#908084
ID:	202408-12

Synopsis

A vulnerability has been discovered in Bitcoin, which can lead to a denial of service.

Background

Bitcoin Core consists of both "full-node" software for fully validating the blockchain as well as a bitcoin wallet.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-p2p/bitcoind	< 25.0	>= 25.0	All supported architectures

Description

Please review the CVE identifier referenced below for details.

Impact

Bitcoin Core, when debug mode is not used, allows attackers to cause a denial of service (CPU consumption) because draining the inventory-to-send queue is inefficient, as exploited in the wild in May 2023.

Workaround

There is no known workaround at this time.

Resolution

All Bitcoin users should upgrade to the latest version:

          # emerge --sync
          # emerge --ask --oneshot --verbose ">=net-p2p/bitcoind-25.0"
