Python up to 3.1.2 accept denial of service

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability labeled as problematic has been found in Python. The impacted element is the function Accept. The manipulation results in denial of service. This vulnerability was named CVE-2010-3492. There is no available exploit. The affected component should be upgraded.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Python (Programming Language Software). Affected is the function accept. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that terminate these applications via network connections.

The weakness was presented 10/19/2010 (Website). The advisory is shared for download at bugs.python.org. This vulnerability is traded as CVE-2010-3492 since 09/24/2010. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 50424 (Mandriva Linux Security Advisory : python (MDVSA-2010:216)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120226 (Solaris Denial of Service Vulnerability in Python).

Upgrading to version 2.1.2 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (50424), SecurityFocus (BID 43233†) and Vulnerability Center (SBV-28040†).
