"The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2019:14142-1 advisory.

  - http.cookiejar.DefaultPolicy.domain_return_ok in Lib/http/cookiejar.py in Python before 3.7.3 does not
    correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An
    attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix
    (e.g., pythonicexample.com to steal cookies for example.com). When a program uses
    http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing
    cookies can be leaked to the attacker. This affects 2.x through 2.7.16, 3.x before 3.4.10, 3.5.x before
    3.5.7, 3.6.x before 3.6.9, and 3.7.x before 3.7.3. (CVE-2018-20852)

  - A security regression of CVE-2019-9636 was discovered in python since commit
    d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through
    v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts
    of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or
    other kind of information, it is possible for an attacker to provide specially crafted URLs to make the
    application locate host-related information (e.g. cookies, authentication data) and send them to a
    different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack
    may vary based on the application. (CVE-2019-10160)

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