Opened: Feb 20, 2014
Severity: 2-Critical

Symptoms

RSA key generation is a time consuming process. Placing a key generation request in an event that is fired frequently can cause TMM to stop responding.

Impact

TMM is killed by SOD.

Conditions

Use CRYPTO::keygen in an event such as CLIENT_DATA or HTTP_REQUEST

Workaround

Move key generation to RULE_INIT.

Fix Information

None
