CVE-2024-28562 identifies a buffer overflow vulnerability in FreeImage version 3.19.0, an open source image processing library widely used for handling various image formats. The vulnerability resides in the Imf_2_2::copyIntoFrameBuffer() function, which is responsible for copying image data when reading EXR (OpenEXR) format files. A buffer overflow occurs when the function improperly handles image data, allowing a local attacker to overwrite memory beyond the intended buffer boundaries. This memory corruption can lead to arbitrary code execution within the context of the affected process. The attack vector requires local access to the system, but no privileges or user interaction are necessary, making it easier for an attacker with local access to exploit. The vulnerability is classified under CWE-787 (Out-of-bounds Write). The CVSS 3.1 base score is 6.8, reflecting medium severity with low confidentiality impact, high integrity impact, and no impact on availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability poses a risk primarily to systems that utilize FreeImage for processing EXR images, which are common in professional graphics, visual effects, and media production environments.

The primary impact of CVE-2024-28562 is the potential for arbitrary code execution by a local attacker, which can compromise the integrity of affected systems. This could lead to unauthorized modification of image data, execution of malicious payloads, or further escalation of privileges if combined with other vulnerabilities. Although the confidentiality impact is low, the ability to execute arbitrary code can allow attackers to manipulate or disrupt workflows involving image processing. Since exploitation requires local access, remote exploitation is not feasible without prior compromise. The absence of availability impact means systems are unlikely to experience denial-of-service conditions directly from this vulnerability. Organizations relying on FreeImage in media production, software development, or any environment processing EXR images are at risk, especially if attackers have local access through insider threats, compromised accounts, or other means.

To mitigate CVE-2024-28562, organizations should first monitor for and apply any official patches or updates released by the FreeImage project addressing this vulnerability. In the absence of patches, consider the following specific mitigations: 1) Restrict local access to systems running FreeImage to trusted users only, minimizing the risk of local exploitation. 2) Employ application whitelisting and endpoint protection solutions to detect and prevent unauthorized code execution. 3) Use sandboxing or containerization for applications processing untrusted EXR images to contain potential exploitation. 4) Implement strict input validation and sanitization on image files before processing, if possible, to detect malformed or malicious EXR files. 5) Monitor system logs and behavior for unusual activity related to image processing components. 6) Educate users and administrators about the risks of processing untrusted image files locally. These targeted mitigations go beyond generic advice by focusing on controlling local access, containment, and proactive detection.
