Scientific Linux Security Update : python on SL4.x, SL5.x i386/x86_64

medium Nessus Plugin ID 61033
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)
