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, which was classified as critical, was found in Calligra 2.4/2.4.1/2.4.2/2.4.3. This affects the function read. 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:

Heap-based buffer overflow in the read function in filters/words/msword-odf/wv2/src/styles.cpp in the Microsoft import filter in Calligra 2.4.3 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted ODF style in an ODF document. NOTE: this is the same vulnerability as CVE-2012-3455, but it was SPLIT by the CNA even though Calligra and KOffice share the same codebase.

The weakness was disclosed 08/20/2012 by Charlie Miller (Website). It is possible to read the advisory at openwall.com. This vulnerability is uniquely identified as CVE-2012-3456 since 06/14/2012. 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 C++. 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 74724 (openSUSE Security Update : calligra (openSUSE-SU-2012:1061-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (77482), Exploit-DB (37576), Tenable (74724), SecurityFocus (BID 54816†) and Secunia (SA50050†). The entry VDB-61714 is pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
