USN-1613-1: Python 2.5 vulnerabilities

First published: Wed Oct 17 2012(Updated: )

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 automatated 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)
