vulnerabilities:

  - Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not
    blocked. (CVE-2020-28948)

  - Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other
    stream-wrapper attack (such as file:// to overwrite files) can still succeed. (CVE-2020-28949)

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