EulerOS 2.0 SP3 : spamassassin (EulerOS-SA-2021-1120)

high Nessus Plugin ID 145177

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the spamassassin package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- SpamAssassin provides you with a way to reduce if not completely eliminate Unsolicited Commercial Email (SPAM) from your incoming email. It can be invoked by a MDA such as sendmail or postfix, or can be called from a procmail script, .forward file, etc. It uses a genetic-algorithm evolved scoring system to identify messages which look spammy, then adds headers to the message so they can be filtered by the user's mail reading software. This distribution includes the spamd/spamc components which create a server that considerably speeds processing of mail.Security Fix(es):In Apache SpamAssassin before 3.4.3, a message can be crafted in a way to use excessive resources.
Upgrading to SA 3.4.3 as soon as possible is the recommended fix but details will not be shared publicly.(CVE-2019-12420)A command execution issue was found in Apache SpamAssassin prior to 3.4.3. Carefully crafted nefarious Configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. This issue is less stealthy and attempts to exploit the issue will throw warnings.
Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.(CVE-2020-1931)

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

Solution

Update the affected spamassassin packages.
