  - 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)

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

  - 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. In Apache SpamAssassin, using     HTML::Parser, we setup an object and hook into the     begin and end tag event handlers In both cases, the     'open' event is immediately followed by a 'close' event
    - even if the tag *does not* close in the HTML being     parsed. Because of this, we are missing the 'text'     event to deal with the object normally. This can cause     carefully crafted emails that might take more scan time     than expected leading to a Denial of Service. The issue     is possibly a bug or design decision in HTML::Parser     that specifically impacts the way Apache SpamAssassin     uses the module with poorly formed html. The exploit     has been seen in the wild but not believed to have been     purposefully part of a Denial of Service attempt. We     are concerned that there may be attempts to abuse the     vulnerability in the future.(CVE-2017-15705)
