Evolution NTLM SASL information disclosure

evolution-ntlmsasl-info-disclosure (49233) The risk level is classified as LowLow Risk

Description:

Evolution could allow a remote attacker to obtain sensitive information, caused by the improper validation of NTLM packets by the NTLM SASL authentication mechanism in Camel. By persuading a victim to connect to a malicious email server, a remote attacker could send specially-crafted NTLM authentication type 2 packets to the ntlm_challenge() function to obtain restricted memory content and other sensitive information.
