Synopsis
The remote machine is affected by multiple vulnerabilities.Description
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)
