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.

A vulnerability was found in gnu gnutls up to 2.6.5 (Network Encryption Software). It has been classified as critical. Affected is some unknown functionality in the library lib/gnutls_pk.c of the component Certificates. The manipulation with an unknown input leads to a cryptographic issues vulnerability (Stored). CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key.

The bug was discovered 04/30/2009. The weakness was shared 04/30/2009 by Miroslav Kratochvil (Website). The advisory is available at article.gmane.org. This vulnerability is traded as CVE-2009-1416 since 04/24/2009. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. This vulnerability is assigned to T1600 by the MITRE ATT&CK project.

A public exploit has been developed by Miroslav Kratochvil in ANSI C and been published immediately after the advisory. 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 40661 (FreeBSD : GnuTLS -- multiple vulnerabilities (b31a1088-460f-11de-a11a-0022156e8794)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 4 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (50260), Tenable (40661) and Exploit-DB (32965). The entries 47995 and 47993 are related to this item.
