"According to the versions of the python packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - In Python (aka CPython) through 3.10.4, the mailcap module does not add escape characters into commands
    discovered in the system mailcap file. This may allow attackers to inject shell commands into applications
    that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or
    arguments). (CVE-2015-20107)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
