Christey" <coley@...us.mitre.org>, Ralph Loader <suckfish@...g.co.nz> Subject: CVE Request -- python-suds: Insecure temporary directory use when initializing file-based URL cache Hello Kurt, Steve, vendors, based on the public Red Hat Bugzilla report:  https://bugzilla.redhat.com/show_bug.cgi?id=978696 by Ralph Loader: A insecure temporary directory use flaw was found in the way python-suds, a Python SOAP web services client library, performed initialization of its internal file-based URL cache (predictable location was used for directory to store the cached files). A local attacker could use this flaw to conduct symbolic link attacks, possibly leading to their ability for example the SOAP .wsdl metadata to redirect queries to a different host, than originally intended. The reasons for the current behaviour are detailed at:  https://bugzilla.redhat.com/show_bug.cgi?id=978696#c4 Could you allocate a CVE id for this? Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team P.S.: There doesn't seem to be an upstream patch available yet (afaik), but the fix is obvious - use more unpredictable routine for file-based URL cache directory location generation than Python's tempfile.gettempdir() (which is case tempfile.tempdir is None, defaults to '/tmp').
