Vulnerability Details
The vulnerability is classified as a heap buffer overflow, which can be triggered in the OpenJPEG project when specific options are specified during the execution of the opj_decompress utility. The CVSS score of 5.6 indicates a medium level of severity, with a local attack vector and low attack complexity. The vulnerability may lead to application crashes with high availability impact, while confidentiality impact is low and integrity impact is none. The vulnerability was published on January 9, 2025.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly validate certain parameters in the opj_decompress utility, leading to a heap buffer overflow. The attack vector is local, requiring attackers to have access to the system where the utility is executed. The attack complexity is low, indicating that an attacker with basic knowledge could exploit this vulnerability. Privileges required are low, and user interaction is required, meaning that a user must execute the vulnerable utility. The confidentiality impact is low, integrity impact is none, and availability impact is high due to the potential for application crashes.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risks, particularly in environments that rely on OpenJPEG for image processing. If exploited, the vulnerability could lead to application crashes, resulting in downtime and possible data loss. Organizations should assess the potential blast radius of this vulnerability, especially if multiple systems utilize the OpenJPEG utility. Given the CVSS score, organizations should address this vulnerability in priority patch cycles.
