Name of the Vulnerable Software and Affected Versions Apache James versions prior to 3.8.1 and 3.7.5

Description A lenient behavior in line delimiter handling might create a difference of interpretation between the sender and the receiver, which can be exploited by an attacker to forge an SMTP envelope, allowing for instance to bypass SPF checks. The issue is related to the enforcement of CRLF as a line delimiter as part of the DATA transaction.

Recommendations For versions prior to 3.8.1, upgrade to version 3.8.1 or later. For versions prior to 3.7.5, upgrade to version 3.7.5 or later.
