The remote Red Hat host is missing one or more security updates.
Updated python packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
Python is an interpreted, interactive, object-oriented programming
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.
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.
