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)

  - Apache SpamAssassin 3.4.2 fixes a local user code     injection in the meta rule syntax.(CVE-2018-11781)

  - 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)

The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2020:4625 advisory.

  - spamassassin: crafted configuration files can run system commands without any output or errors     (CVE-2018-11805)

  - spamassassin: crafted email message can lead to DoS (CVE-2019-12420)

  - spamassassin: command injection via crafted configuration file (CVE-2020-1930, CVE-2020-1931)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Update to 3.4.4. Fixes CVE-2020-1930 and CVE-2020-1931.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4265-1 advisory.

    It was discovered that SpamAssassin incorrectly handled certain CF files. If a user or automated system     were tricked into using a specially-crafted CF file, a remote attacker could possibly run arbitrary code.
