httplib2 0.7.2, 0.8, and earlier, after an initial connection is made, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

The remote NewStart CGSL host, running version MAIN 6.06, has python-httplib2 packages installed that are affected by a vulnerability:

  - httplib2 0.7.2, 0.8, and earlier, after an initial connection is made, does not verify that the server     hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509     certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid     certificate. (CVE-2013-2037)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - httplib2 0.7.2, 0.8, and earlier, after an initial connection is made, does not verify that the server
    hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509
    certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid
    certificate. (CVE-2013-2037)

Add patch to fix http over proxy. Fixes bug #857514

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that httplib2 only validated SSL certificates on the first request to a connection, and didn't report validation failures on subsequent requests. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could possibly be exploited in certain scenarios to alter or compromise confidential information in applications that used the httplib2 library.

Updated python-httplib2 packages fix security vulnerability :

httplib2 only validates SSL certificates on the first request to a connection, and doesn't report validation failures on subsequent requests (CVE-2013-2037).
