CVE ID         : CVE-2016-1238 CVE-2017-15705 CVE-2018-11780 CVE-2018-11781
Debian Bug     : 784023 865924 883775 889501 891041 908969 908970 908971 913571

Multiple vulnerabilities were found in Spamassassin, which could lead
to Remote Code Execution and Denial of Service attacks under certain
circumstances.

CVE-2016-1238

    Many Perl programs do not properly remove . (period) characters
    from the end of the includes directory array, which might allow
    local users to gain privileges via a Trojan horse module under the
    current working directory.

CVE-2017-15705

    A denial of service vulnerability was identified that exists in
    Apache SpamAssassin before 3.4.2. The vulnerability arises with
    certain unclosed tags in emails that cause markup to be handled
    incorrectly leading to scan timeouts. This can cause carefully
    crafted emails that might take more scan time than expected
    leading to a Denial of Service.

CVE-2018-11780

    A potential Remote Code Execution bug exists with the PDFInfo
    plugin in Apache SpamAssassin before 3.4.2.

CVE-2018-11781

    Apache SpamAssassin 3.4.2 fixes a local user code injection in the
    meta rule syntax.

For Debian 8 "Jessie", these problems have been fixed in version
3.4.2-0+deb8u1. Upstream strongly advocates upgrading to the latest
upstream version so we are following that recommendation and
backported the version published as part of the 9.6 stretch release,
which also fixes many critical bugs.

We recommend that you upgrade your spamassassin packages.
