For Debian 8 'Jessie', these problems have been fixed in version 3.4.2-0+deb8u3.

We recommend that you upgrade your spamassassin packages.

The remote NewStart CGSL host, running version MAIN 6.02, has spamassassin packages installed that are affected by multiple vulnerabilities:

  - 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     rule configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. With     this bug unpatched, exploits can be injected in a number of scenarios including the same privileges as     spamd is run which may be elevated 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. If you cannot upgrade, do not use 3rd party rulesets, do not use sa-compile and do not run spamd     as an account with elevated privileges. (CVE-2020-1930)

  - 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)

  - In Apache SpamAssassin before 3.4.3, nefarious CF files can be configured to run system commands without     any output or errors. With this, exploits can be injected in a number of scenarios. In addition to     upgrading to SA 3.4.3, we recommend that users should only use update channels or 3rd party .cf files from     trusted places. (CVE-2018-11805)
