Integer Overflow in libtiff's rgb2ycbcr Utility Affecting Image Processing

CVE-2026-52492

What is CVE-2026-52492?

A vulnerability in the libtiff library's rgb2ycbcr utility can be exploited due to an integer overflow in the cvtRaster() function. This flaw occurs when calculating the strip buffer sizes, which can lead to undersized heap allocations. When a specially crafted TIFF image is processed, this can cause a heap-based buffer overflow, potentially allowing attackers to execute arbitrary code or disrupt the application’s behavior.
