The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:0491 advisory.

    Python is an interpreted, interactive, object-oriented programming     language.

    A flaw was found in the Python urllib and urllib2 libraries where they     would not differentiate between different target URLs when handling     automatic redirects. This caused Python applications using these modules to     follow any new URL that they understood, including the file:// URL type.
    This could allow a remote server to force a local Python application to     read a local file instead of the remote one, possibly exposing local files     that were not meant to be exposed. (CVE-2011-1521)

    Multiple flaws were found in the Python audioop module. Supplying certain     inputs could cause the audioop module to crash or, possibly, execute     arbitrary code. (CVE-2010-1634, CVE-2010-2089)

    A race condition was found in the way the Python smtpd module handled new     connections. A remote user could use this flaw to cause a Python script     using the smtpd module to terminate. (CVE-2010-3493)

    An information disclosure flaw was found in the way the Python     CGIHTTPServer module processed certain HTTP GET requests. A remote attacker     could use a specially-crafted request to obtain the CGI script's source     code. (CVE-2011-1015)

    A buffer over-read flaw was found in the way the Python Expat parser     handled malformed UTF-8 sequences when processing XML files. A     specially-crafted XML file could cause Python applications using the Python     Expat parser to crash while parsing the file. (CVE-2009-3720)

    This update makes Python use the system Expat library rather than its own     internal copy; therefore, users must have the version of Expat shipped with     RHSA-2009:1625 installed, or a later version, to resolve the CVE-2009-3720     issue.

    All Python users should upgrade to these updated packages, which contain     backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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