Ubuntu Security Notice (C) 2012-2014 Canonical, Inc. / NASL script (C) 2012-2014 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
It was discovered that Python would prepend an empty string to
sys.path under certain circumstances. A local attacker with write
access to the current working directory could exploit this to execute
arbitrary code. (CVE-2008-5983)
It was discovered that the audioop module did not correctly perform
input validation. If a user or automated system were tricked into
opening a crafted audio file, an attacker could cause a denial of
service via application crash. (CVE-2010-1634, CVE-2010-2089)
Giampaolo Rodola discovered several race conditions in the smtpd
module. A remote attacker could exploit this to cause a denial of
service via daemon outage. (CVE-2010-3493)
It was discovered that the CGIHTTPServer module did not properly
perform input validation on certain HTTP GET requests. A remote
attacker could potentially obtain access to CGI script source files.
Niels Heinen discovered that the urllib and urllib2 modules would
process Location headers that specify a redirection to file: URLs. A
remote attacker could exploit this to obtain sensitive information or
cause a denial of service. (CVE-2011-1521)
It was discovered that SimpleHTTPServer did not use a charset
parameter in the Content-Type HTTP header. An attacker could
potentially exploit this to conduct cross-site scripting (XSS) attacks
against Internet Explorer 7 users. (CVE-2011-4940)
It was discovered that Python distutils contained a race condition
when creating the ~/.pypirc file. A local attacker could exploit this
to obtain sensitive information. (CVE-2011-4944)
It was discovered that SimpleXMLRPCServer did not properly validate
its input when handling HTTP POST requests. A remote attacker could
exploit this to cause a denial of service via excessive CPU
It was discovered that the Expat module in Python 2.5 computed hash
values without restricting the ability to trigger hash collisions
predictably. If a user or application using pyexpat were tricked into
opening a crafted XML file, an attacker could cause a denial of
service by consuming excessive CPU resources. (CVE-2012-0876)
Tim Boddy discovered that the Expat module in Python 2.5 did not
properly handle memory reallocation when processing XML files. If a
user or application using pyexpat were tricked into opening a crafted
XML file, an attacker could cause a denial of service by consuming
excessive memory resources. (CVE-2012-1148).
Update the affected python2.5 and / or python2.5-minimal packages.
