Description Vasyl Kaigorodov 2014-11-07 14:51:24 UTC

    https://github.com/requests/requests-kerberos/pull/36
    https://github.com/mkomitee/requests-kerberos/commit/9c1e08cc17bb6950455a85d33d391ecd2bce6eb6
    https://pypi.python.org/pypi/requests-kerberos


    A fix was merged and released today for the package which performs
    kerberos authentication when using python-requests. Prior to this,
    every version of the package did not properly handle mutual
    authentication which means that the client did not verify that the
    user was communicating with a trusted server. The version which
    contains the fix is 0.6 and all prior versions are considered
    vulnerable.


    This bug, however, prevented the mutual authentication code from being
    executed, so it's possible that users think they're talking to a
    trusted server, but they're not.


    requests_kerberos/kerberos_.py


    Make certain that responses always pass through handle_other() to provide mutual
    authentication before returning them to the user.

This is a dupe of bug 1160540. I guess you just want to set the CVE ID on that other bug so your scripts find it properly.
