GNU lsh 2.0.1 File Descriptors unix_random.c information disclosure

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.

Detailsinfo

A vulnerability classified as problematic has been found in GNU lsh 2.0.1. This affects an unknown code of the file unix_random.c of the component File Descriptors. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality, and availability. The summary by CVE is:

unix_random.c in lshd for lsh 2.0.1 leaks file descriptors related to the randomness generator, which allows local users to cause a denial of service by truncating the seed file, which prevents the server from starting, or obtain sensitive seed information that could be used to crack keys.

The bug was discovered 01/20/2006. The weakness was released 01/20/2006 by Stefan Pfetzing (Website). It is possible to read the advisory at lists.lysator.liu.se. This vulnerability is uniquely identified as CVE-2006-0353 since 01/22/2006. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1592 according to MITRE ATT&CK.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 22822 (Debian DSA-956-1 : lsh-server - filedescriptor leak), which helps to determine the existence of the flaw in a target environment.
