Описание

A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.26 handled component references in CDEF box in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.

A NULL pointer dereference flaw was found in Jasper in the way it handled component references in the CDEF box in the JP2 image format decoder. This flaw allows a specially crafted JP2 image file to cause an application using the Jasper library to crash when opened. The highest threat from this vulnerability is system availability.

Отчет

Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-476: NULL Pointer Dereference vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. The platform incorporates secure engineering principles and controls to enforce secure coding practices, including proper memory handling and error checking, reducing the likelihood of null pointer dereference vulnerabilities. Coding standards, tools, and processes support early detection and prevention of memory-related flaws. Static code analysis identifies null dereference and related issues during development, while system monitoring detects memory errors and anomalous behavior in the event of exploitation. Additionally, the platform leverages memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to strengthen resilience against memory-related vulnerabilities.
