Image-Processing

Thumbor version 7.7.7 and earlier is vulnerable to arbitrary file read via a path traversal flaw in file_loader.py, where security checks are performed before decoding percent-encoded traversal sequences.

A critical out-of-bounds read vulnerability (CVE-2026-66759) has been identified in the GIMP file-icns plugin, where processing a crafted ICNS file with a truncated mask resource can lead to information disclosure of heap contents via leaked alpha channel pixel values or a denial of service due to an application crash.

Multiple high-severity vulnerabilities, including CVE-2026-33327, CVE-2026-33328, CVE-2026-35590, and CVE-2026-35591, have been identified and patched in the libvips dependency used by the sharp image processing library, affecting users processing untrusted input with sharp versions prior to 0.35.0 or globally installed libvips prior to 8.18.3.

A vulnerability (CVE-2026-55379) in Pillow's BdfFontFile component allows attackers to craft a malicious BDF font file with oversized BBX dimensions and an empty BITMAP section, bypassing documented decompression bomb protection and causing the Image.new() function to silently allocate large amounts of memory in the C-heap, leading to resource exhaustion and denial-of-service for applications processing untrusted BDF fonts.

The Pillow library contains an out-of-bounds read vulnerability in its McIdas AREA plugin when processing specially crafted image files opened from a filename, allowing an attacker to manipulate header words to define a 'stride' value smaller than the actual row width, leading to information disclosure through adjacent process memory leakage or denial of service due to a process crash (SIGBUS).

A remote, anonymous attacker can exploit a vulnerability in the GraphicsMagick PCD decoder to potentially execute arbitrary code, corrupt memory, or cause a denial-of-service condition. This flaw could lead to compromise of the system running the affected software or disruption of its availability.

A heap buffer overflow vulnerability (CVE-2026-58379) in GIMP's Paint Shop Pro (PSP) file format parser allows a remote attacker to achieve arbitrary code execution or cause a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file, exploiting incorrect buffer size calculations when processing low bit-depth images.

A heap buffer over-write vulnerability exists in ImageMagick's IPL decoder when processing multiple images of different dimensions, affecting Magick.NET packages prior to version 14.13.1 and potentially leading to arbitrary code execution.

A memory access vulnerability exists in the SAIL image library's XWD codec due to inconsistent handling of pixel format, potentially leading to crashes or code execution when processing specially crafted image files.

A heap buffer overflow vulnerability exists in the SAIL image loading library's PSD codec due to a mismatch in bytes-per-pixel calculation and pixel buffer allocation in LAB mode, leading to potential code execution.
