FKIE_CVE-2012-4684
Vulnerability from fkie_nvd - Published: 2013-03-12 11:28 - Updated: 2026-06-16 23:45
Severity
Summary
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.
