CVE-2026-120435

Netpbm before 10.86.51, 11.02.30, and 11.15.08 Heap Overflow in xpmtoppm

Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains a heap buffer overflow in xpmtoppm caused by an unvalidated characters-per-pixel value in the XPM header. Attackers can supply a crafted XPM file with characters-per-pixel greater than 3 to overrun fixed 3-byte colorName hash entries, causing crashes or potentially code execution.

CVE-2026-120434

Netpbm before 10.86.51, 11.02.30, and 11.15.08 picttoppm Stack Overflow via scanPoly

Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains a stack-based buffer overflow in picttoppm's scanPoly() function in converter/ppm/picttoppm.c. Attackers can supply a crafted PICT file whose polygon edges produce more than 5000 points, overflowing the coord stack array to crash the converter or potentially execute code.

CVE-2026-120436

Netpbm before 10.86.51, 11.02.30, and 11.15.08 Heap Overflow via jbigtopnm

Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains an integer overflow in jbigtopnm that causes heap buffer overflow when computing output buffer size. Attackers can supply a crafted multi-plane JBIG file with large header dimensions so jbg_dec_merge_planes() overflows the undersized buffer, causing crashes or potentially code execution.

CVE-2026-120437

Netpbm before 10.86.51, 11.02.30, and 11.15.08 Out-of-Bounds Read via tgatoppm

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.

CVE-2026-120433

Netpbm before 10.86.51, 11.02.30, and 11.15.08 picttoppm Stack Buffer Overflow via paintPoly

Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains a stack-based buffer overflow in the picttoppm paintPoly() function due to an unbounded polygon point count. Attackers can supply a crafted PICT file with a polygon exceeding 100 points to overwrite the fixed pts array, causing crashes or potentially code execution.

CVE-2026-120432

Netpbm before 10.86.51, 11.02.30, and 11.15.08 Integer Overflow in winicontopam

Netpbm before 10.86.51, 11.02.30, and 11.15.08 contains an integer overflow vulnerability in winicontopam that allows attackers to corrupt heap memory via oversized ICO/CUR dimensions. Attackers can supply a crafted icon file with width or height above 32767, wrapping int16_t loop counters into negative row buffer indices to cause crashes or potential code execution.

CVE-2026-112276

Netpbm through 11.16.00 Heap Out-of-Bounds Read via rasttopnm Colormap

Netpbm through 11.16.00 contains a heap out-of-bounds read vulnerability in rasttopnm that allows attackers to read heap memory by supplying Sun rasterfiles with short colormaps. Attackers can craft colormapped rasterfiles with pixel bytes exceeding the palette length to leak up to 255 adjacent heap bytes into the PNM output or crash the program.

CVE-2026-112275

Netpbm through 11.16.00 Heap Out-of-Bounds Write via rasttopnm pr_load_image

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.
