CVE-2026-106063— Gimp: gimp: heap buffer overflow in dicom export on oversized image dimensions

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
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.

在 GIMP 的 DICOM 导出插件中发现了一个基于堆的缓冲区溢出漏洞。当导出宽度或高度极大的图像时，导出路径会使用 32 位整数计算“宽度 × 高度 × 每像素字节数”来分配缓冲区，该乘法运算可能发生整数溢出，导致分配的缓冲区大小不足。随后，GEGL 会将完整的未压缩图像数据写入这个尺寸过小的缓冲区中（CWE-787），从而引发堆缓冲区溢出。

Vulnerability Title
Gimp: gimp: heap buffer overflow in dicom export on oversized image dimensions
Source: CVE Program / CVE List V5
Vulnerability Description
A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer (CWE-787), after integer overflow in the allocation size
