CVE-2026-31806 FreeRDP has a Heap Buffer Overflow in nsc_process_message() via Unchecked SURFACE_BITS_COMMAND Bitmap Dimensions

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, the gdisurfacebits function processes SURFACEBITSCOMMAND messages sent by the RDP server. When the command is handled using NSCodec, the bmp.width and bmp.height values provided by the server are not properly...

CVE-2026-31806

Summary: CVE-2026-31806 affects FreeRDP prior to 3.24.0, where the gdi_surface_bits() handler (NSCodec path) can process SURFACE_BITS_COMMAND messages with unsafe bmp.width/bmp.height values, enabling a heap buffer overflow by crafting server data. The issue arises when width/height are not prope...

PYSEC-2026-2258

pillowheif is a Python library for working with HEIF images and plugin for Pillow. Prior to version 1.3.0, an integer overflow in the encode path buffer validation of pillowheif.c allows an attacker to bypass bounds checks by providing large image dimensions, resulting in a heap out-of-bounds rea...

CVE-2026-28231 pillow_heif Has Integer Overflow in Encode Path Buffer Validation that Leads to Heap Out-of-Bounds Read

pillowheif is a Python library for working with HEIF images and plugin for Pillow. Prior to version 1.3.0, an integer overflow in the encode path buffer validation of pillowheif.c allows an attacker to bypass bounds checks by providing large image dimensions, resulting in a heap out-of-bounds rea...

CVE-2026-27798

A flaw was found in ImageMagick. A local user could exploit a heap buffer over-read vulnerability by processing a specially crafted image with small dimensions using the -wavelet-denoise operator. This vulnerability may lead to the disclosure of sensitive information. Mitigation To reduce exposur...

GHSA-VHQJ-F5CJ-9X8H ImageMagick has heap-buffer-overflow via signed integer overflow in WriteUHDRImage when writing UHDR images with large dimensions

WriteUHDRImage in coders/uhdr.c uses int arithmetic to compute the pixel buffer size. When image dimensions are large, the multiplication overflows 32-bit int, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of...
