PatchTheCVECVE-2026-120437: Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains an out-of-bounds read vulnera
CVE-2026-120437 is a medium-severity flaw (CVSS 6.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
