Description Marian Rehak 2026-11-06 04:10:43 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
