CVE-2012-4684

Name of the Vulnerable Software and Affected Versions bitcoind and Bitcoin-Qt versions prior to 0.7.0

Description The issue concerns the alert functionality in the affected software, which improperly handles different character representations of the same signature data. It relies on a hash of this signature, allowing remote attackers to cause a denial of service through resource consumption by providing a valid modified signature for a circulating alert.

Recommendations For versions prior to 0.7.0, update to version 0.7.0 or later to resolve the issue.
