Detailsinfo

A vulnerability, which was classified as critical, was found in Python 2.7/3.3.3 (Programming Language Software). This affects the function sock_recvfrom_into. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the socket.recvfrom_into function in Modules/socketmodule.c in Python 2.5 before 2.7.7, 3.x before 3.3.4, and 3.4.x before 3.4rc1 allows remote attackers to execute arbitrary code via a crafted string.

The weakness was published 01/14/2014 by Ryan Smith-Roberts (rmsr) as buffer overflow in socket.recvfrom_into as confirmed advisory (Website). The advisory is shared at bugs.python.org. The public release has been coordinated with the project team. This vulnerability is uniquely identified as CVE-2014-1912 since 02/07/2014. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in Python. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 75320 (openSUSE Security Update : python (openSUSE-SU-2014:0518-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350417 (Amazon Linux Security Advisory for python26: AL2012-2015-094).

Applying the patch Fix is able to eliminate this problem. The bugfix is ready for download at bugs.python.org. A possible mitigation has been published 3 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (90931), Exploit-DB (31875), Tenable (75320), SecurityFocus (BID 65379†) and Secunia (SA56624†). Similar entries are available at VDB-12200, VDB-66486 and VDB-104082. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
