Doc Text:

Description Sam Fowler 2018-09-16 23:15:42 EDT 
Apache SpamAssassin before version 3.4.2 is vulnerable to a denial of service in the handling of crafted email. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts.
