New Debian spamassassin 3.4.2-1~deb9u3 fixes:
This update addresses the following issues:
* 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.
