Descripción técnica

A flaw was found in the file-pcx plugin in GIMP, affecting 32-bit builds only. When processing a PCX image file, the plugin calculates memory allocation sizes based on the image dimensions and the number of color planes. If a crafted file sets the number of planes to 4 alongside sufficiently large dimensions, the calculation exceeds the 32-bit integer limit and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when the plugin subsequently writes image data into the undersized buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service.

——1GNU Emacs before 31.0.91 contains an integer overflow in the PBM/PPM/PGM image loader that allows an attacker to leak heap memory contents by supplying a crafted image with large dimensions and an elevated max color index. The image loader multiplies image dimensions and channel count using signed integer arithmetic; for sufficiently large values, the result wraps to a negative number, bypassing the bounds check and causing the pixel reader to access heap memory past the end of the allocated buffer. The over-read contents are interpreted as pixel color values and rendered on screen.6d CVE-2026-502786.5 MED

——5iccDEV provides a set of libraries and tools for working with ICC color management profiles. Versions prior to 2.3.2.1 have a `CIccEmbedIO::Read8()` size_t underflow. The issue arises due to an embedded-profile read defect when parsing ICC profiles containing `icSigEmbeddedV5ProfileTag` data with `icSigEmbeddedProfileType` payloads. Version 2.3.2.1 patches the issue. No known workarounds are available.6d CVE-2026-694198.5 ALT
