The remote Ubuntu host is missing one or more security-related
USN-1613-1 fixed vulnerabilities in Python 2.5. This update provides
the corresponding updates for Python 2.4.
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.
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. (CVE-2011-1015)
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.
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.
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 utilization. (CVE-2012-0845)
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.
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.
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 python2.4 and / or python2.4-minimal packages.
