CVE-2026-102834— JavaCV: Integer Overflow in IPCameraFrameGrabber Causes Infinite-Loop DoS

Quick assessment

Affected
bytedeco javacv
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

JavaCV 为 OpenCV、FFmpeg 及其他多媒体库提供 Java 接口。在 1.5.14 版本之前，IPCameraFrameGrabber 在分配 32 位缓冲区容量时将其翻倍，但未检查是否发生溢出，也未对解析后的 Content-Length 进行边界限制。若应用程序从恶意的摄像头端点或经过篡改的明文流中消费 MJPEG 响应，攻击者可利用该漏洞返回一个超大的 Content-Length 头部。成功利用此漏洞会导致抓取帧的线程陷入永久 CPU 自旋循环，从而造成拒绝服务（DoS）。该问题已在 1.5

Vulnerability Title
JavaCV: Integer Overflow in IPCameraFrameGrabber Causes Infinite-Loop DoS
Source: CVE Program / CVE List V5
Vulnerability Description
JavaCV provides Java interfaces to OpenCV, FFmpeg, and other multimedia libraries. Prior to 1.5.14, IPCameraFrameGrabber doubles a 32-bit buffer capacity without checking for overflow or bounding the parsed Content-Length. An application consumes an MJPEG response from a malicious camera endpoint or a tampered plaintext stream. The source can return an oversized Content-Length header in an MJPEG stream. Successful exploitation can trap the frame-grabbing thread in a permanent CPU-spinning loop and deny service. This issue is fixed in version 1.5.14.
