CVE-2026-92248— Gimp: integer overflow when generating a thumbnail preview for a psd file
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.
GIMP 中的 file-psd 插件存在一个缺陷。在为精心构造的 PSD（Photoshop Document）图像文件生成缩略图预览时，在解析内嵌 JPEG 头部中的数值进行乘法运算时发生整数溢出。这导致了堆分配内存不足，进而当图像数据被解码时引发基于堆的缓冲区溢出。该缓冲区溢出会破坏相邻的堆对象，从而实现受控的内存写入，可能导致应用程序崩溃或任意代码执行。

Vulnerability Title
Gimp: integer overflow when generating a thumbnail preview for a psd file
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.
