CVE-2012-4684
CWE-399Published: March 12, 2013· Updated: Jun 16, 2026
7.8
CVSS v3.1
Official Description
The alert functionality in bitcoind and Bitcoin-Qt before 0.7.0 supports different character representations of the same signature data, but relies on a hash of this signature, which allows remote attackers to cause a denial of service (resource consumption) via a valid modified signature for a circulating alert.
Technical Analysis
CVE-2012-4684 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
