Doc Text:
A flaw was found in netpbm. An attacker could exploit this vulnerability by enticing a user to process a specially crafted Sun raster image file using the rasttopnm conversion utility. A heap-based buffer overflow in the run-length decoder allows out-of-bounds data to be written into memory. Successful exploitation can lead to a Denial of Service (DoS) through application crashes or cause memory corruption.

Description OSIDB Bzimport 2026-10-19 14:20:40 UTC
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.
