CVE-2013-3219: Bitcoin Core

Medium severity, CVSS 5.0. EPSS: 2% chance of exploitation in the next 30 days.

bitcoind and Bitcoin-Qt 0.8.x before 0.8.1 do not enforce a certain block protocol rule, which allows remote attackers to bypass intended access restrictions and conduct double-spending attacks via a large block that triggers incorrect Berkeley DB locking in older product versions.

Affected products

• Bitcoin Bitcoin Core: version 0.8.0 only
