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."], "mitigation": {"lang": "en:us", "value": "Users should avoid opening untrusted DirectDraw Surface (DDS) image files with GIMP. As a general security practice, only process files from trusted sources. If GIMP is not essential, consider removing the `gimp` package to eliminate this attack vector."}, "name": "CVE-2026-42170", "public_date": "2026-08-04T00:19:42Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-42170\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-42170"], "statement": "This heap-based buffer overflow vulnerability in the GIMP DDS plug-in could lead to heap metadata corruption and potential code execution. The flaw is triggered when a user opens a specially crafted DDS image file. Red Hat Enterprise Linux systems with GIMP installed are affected if users process untrusted DDS files.", "threat_severity": "Important"}
