The remote Ubuntu host is missing one or more security-related
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).
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected python2.5 and / or python2.5-minimal packages.
