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, which was classified as critical, was found in LibTIFF 4.0/4.0.1/4.0.2 (Image Processing Software). Affected is an unknown functionality of the file gif2tiff.c of the component GIF File Extension Block Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The software 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 weakness was presented 08/01/2013 by Pedro Ribeiro as Four (stack-based) buffer overflows and one use-after-free in libtiff v4.0.3 as not defined mailinglist post (oss-sec). The advisory is shared for download at seclists.org. The public release happened without coordination with the vendor. This vulnerability is traded as CVE-2013-4231 since 06/12/2013. The exploitability is told to be difficult. 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 real existence of this vulnerability is still doubted at the moment. The vulnerability scanner Nessus provides a plugin with the ID 75146 (openSUSE Security Update : tiff (openSUSE-SU-2013:1482-1)), 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 local. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350364 (Amazon Linux Security Advisory for libtiff: ALAS-2014-365).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (75146). Further details are available at asmail.be. See 9947, 9949, 9950 and 9951 for similar entries.
