NVD description

A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.

    🚨High - GIMP PNM Parser Off-by-One Stack Overflow (CVE-2026-58380) An off-by-one error in GIMP's PNM image parser causes pnmscanner_gettoken() to write a null terminator one byte past the end of a stack buffer when reading a specially crafted PNM file. The out-of-bounds write corrupts adjacent stack memory, leading to a crash (DoS) or, depending on memory layout, potential arbitrary code execution in the context of the user who opened the file. Exploitation is local and requires user interaction — the victim must open a malicious PNM file in GIMP — so the realistic vector is a booby-trapped image delivered via email, download, or file share (CVSS 7.3, Red Hat). 👉Fixed upstream in GNOME GIMP (commit 83699817); gimp on RHEL 7/8/9 listed as affected.

    Post summary

    The post describes an off‑by‑one stack overflow in GIMP’s PNM parser that can lead to DoS or code execution (CVSS 7.3) and notes the vulnerability has been fixed upstream (commit 83699817) with patches for RHEL 7/8/9.
