CVE-2026-42170— Gimp: gimp dds plug-in heap-based buffer overflow via bpp mismatch in load_layer() (ddsread.c)

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 6
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 DDS是GIMP组织的一款图像编辑软件的插件。 GIMP DDS存在缓冲区错误漏洞，该漏洞源于DDS文件解析器在处理特制的DDS文件时，对像素格式和每像素位数验证不足，导致分配过小的堆缓冲区，造成堆缓冲区溢出，可能导致代码执行。

Vulnerability Title
Gimp: gimp dds plug-in heap-based buffer overflow via bpp mismatch in load_layer() (ddsread.c)
Source: CVE Program / CVE List V5
Vulnerability Description
A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corruption and potential code execution.
