OpenJPEG up to 2.1.1 convert.c s null pointer dereference

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

A vulnerability, which was classified as critical, was found in OpenJPEG up to 2.1.1 (Image Processing Software). This affects some unknown functionality of the file convert.c. The manipulation of the argument s with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

convert.c in OpenJPEG before 2.1.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors involving the variable s.

The weakness was published 10/03/2016 (Website). The advisory is shared at This vulnerability is uniquely identified as CVE-2016-7445 since 09/09/2016. 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 are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 93824 (openSUSE Security Update : openjpeg (openSUSE-2016-1139)), 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 l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 169669 (OpenSuSE Security Update for openjpeg2 (openSUSE-SU-2017:0185-1)).

Upgrading to version 2.1.2 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (93824) and SecurityFocus (BID 93040†). Similar entries are available at VDB-55902 and VDB-137105.
