Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A flaw was found in the way a local user on the SpamAssassin server could inject code in the meta rule syntax. This could cause the arbitrary code execution on the server when these rules are being processed.(CVE-2018-11781)

A potential Remote Code Execution bug exists with the PDFInfo plugin in Apache SpamAssassin before 3.4.2.(CVE-2018-11780)

A flaw was found in the way SpamAssassin processes HTML email containing unclosed HTML tags. A carefully crafted mail message could cause SpamAssassin to consume significant resources. If a large number of these messages are sent, a denial of service could occur potentially delaying or preventing the delivery of email.(CVE-2017-15705)

Solution

Run 'yum update spamassassin' to update your system.
