Description

Two vulnerabilities were discovered in spamassassin, a Perl-based spam filter using text analysis.

CVE-2018-11805

Malicious rule or configuration files, possibly downloaded from an updates server, could execute arbitrary commands under multiple scenarios.

CVE-2019-12420

Specially crafted mulitpart messages can cause spamassassin to use excessive resources, resulting in a denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 3.4.2-0+deb8u2.

We recommend that you upgrade your spamassassin packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
