patch available.

  - In Python (aka CPython) up to 3.10.8, 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). The fix is also back-ported to 3.7, 3.8, 3.9 (CVE-2015-20107)

Note that Nessus relies on the presence of the package as reported by the vendor.");
