Doc Text:
A flaw was found in Netpbm. The tgatoppm converter fails to validate pixel values against color map bounds in the get_pixel() function. By supplying a specially crafted color-mapped Targa file, an attacker can trigger an out-of-bounds read. This flaw can lead to a Denial of Service (DoS) through an application crash or result in information disclosure by leaking adjacent memory into the generated image.

Description OSIDB Bzimport 2026-11-02 16:49:24 UTC
Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains an out-of-bounds read vulnerability in the tgatoppm converter's get_pixel() function that uses unchecked pixel values as color map indexes. Attackers can supply a crafted color-mapped Targa file whose pixel values exceed the declared color map bounds to crash the converter or leak adjacent memory into the output image.
