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

Medium Nessus Plugin ID 62620

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).

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.

Solution

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