Uncontrolled Resource Consumption

dompdf/dompdf is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to the library trusting attacker-controlled BMP header dimensions without validating the image size before conversion, which allows an attacker to embed a crafted BMP image e.g., via a data:image/bmp;base64...

PT-2026-64433

Name of the Vulnerable Software and Affected Versions Cloudreve versions prior to 4.17.0 Description Cloudreve contains an issue where the built-in image decoders for PNG, JPEG, and GIF formats limit only the compressed file size but do not restrict the decoded pixel dimensions. An authenticated...

GHSA-5QJQ-93H5-HRGP pypdf: Possible large memory usage for wrong image dimensions

Impact An attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires loading images where the declared size values are much too large compared to the actual data. Patches This has been fixed in pypdf==6.14.0. Workarounds If you cannot upgrade yet, consid...

kernel: drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs()

A flaw was found in the Linux kernel's Direct Rendering Manager DRM Graphics Execution Manager GEM component. This vulnerability arises from an inconsistent calculation of plane dimensions, which can lead to incorrect memory allocation checks. A local attacker could exploit this by creating a...

Dompdf: Uncontrolled resource consumption based on declared BMP dimensions

Summary dompdf accepts a BMP image and generates a PDF-compatible PNG based only on its declared header dimensions and never bounds width × height before the image is converted through GD. A 58-byte BMP whose header declares e.g. 6000×6000 is accepted and later drives imagecreatetruecolor$width,...

Pillow `GdImageFile._open()`: image dimensions accepted without `_decompression_bomb_check()`

Description PIL/GdImageFile.py GdImageFile.open reads image dimensions from the GD 2.x header and stores them in self.size without calling Image.decompressionbombcheck. Because GdImageFile is not registered with Image.registeropen, it never passes through the standard Image.open code path that...
