Ubuntu 8.04 LTS : python2.4 vulnerabilities (USN-1613-2)

Ubuntu Security Notice (C) 2012-2014 Canonical, Inc. / NASL script (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.
(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. (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.
(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 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.
(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).

Solution :

Update the affected python2.4 and / or python2.4-minimal packages.

Risk factor :

Medium / CVSS Base Score : 6.9
