Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Aki Tuomi reports :

lib-smtp doesn't handle truncated command parameters properly, resulting in infinite loop taking 100% CPU for the process. This happens for LMTP (where it doesn't matter so much) and also for submission-login where unauthenticated users can trigger it.

Aki also reports :

Snippet generation crashes if :

message is large enough that message-parser returns multiple body blocks The first block(s) don't contain the full snippet (e.g. full of whitespace) input ends with '>'

Solution

Update the affected package.
