Python < 2.7.4, 3.2.x < 3.2.4 Vulnerability in the utf-16 decoder after error handling (bpo-14579) - Linux
Published: 2021-11-01 10:45:13
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:N/A:P
Detection Type:
Remote Banner Unreliable
Solution Type:
Vendor Patch
Summary:
Python is prone to a vulnerability in the UTF-16 decoder.
Detection Method:
Checks if a vulnerable version is present on the target host.
Technical Details:
The utf-16 decoder in Python does not update the aligned_end
variable after calling the unicode_decode_call_errorhandler function, which allows remote
attackers to obtain sensitive information (process memory) or cause a denial of service (DoS)
(memory corruption and crash) via unspecified vectors.
Affected Versions:
Python prior to version 2.7.4 and 3.2.x prior to 3.2.4.
Recommendations:
Update to version 2.7.4, 3.2.4 or later.

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
