Description Vladimir Vasilev 2026-10-20 15:00:28 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 through 11.16.00 contains a heap out-of-bounds write vulnerability in the rasttopnm Sun rasterfile run-length decoder pr_load_image in converter/other/rast.c. Attackers can supply a byte-encoded rasterfile with tiny dimensions and a long run-length body to write controlled bytes past md_image, causing memory corruption and crashes.
