CVE-2026-120437: Netpbm tgatoppm out-of-bounds read in color map indexing

CVE-2026-120437 · Severity: medium · CVSS 6.1 · Published 2026-11-02

Netpbm is a toolkit for image format conversion that includes tgatoppm, a converter for Targa image files. A flaw in tgatoppm's get_pixel() function allows an attacker to supply a malicious Targa file with invalid color map indexes, causing the converter to read beyond the color map bounds. This can crash the converter or expose sensitive adjacent memory in the output image.

How to fix

Fixed in: 10.86.51, 11.02.30, 11.15.08

Technical details

The tgatoppm converter's get_pixel() function uses pixel values directly as color map indexes without validating they fall within the declared color map bounds, resulting in an out-of-bounds read. An attacker can craft a color-mapped Targa file with pixel values exceeding the color map size to trigger the vulnerability. The flaw allows information disclosure via memory leakage into the output image or denial of service through a crash.
