Sicherheitslücken in graphicsmagick

GraphicsMagick WPG File wpg.c ExtractPostscript recursion

A vulnerability was detected in GraphicsMagick up to 1.3.47. Affected by this vulnerability is the function ExtractPostscript of the file coders/wpg.c of the component WPG File Handler. Performing a manipulation results in uncontrolled recursion. The attack may be initiated remotely. The patch is named 627b5b1b2fc2. It is suggested to install a patch to address this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

Out-of-bounds write in GraphicsMagick PCD decoder

A heap out-of-bounds write exists in the Photo CD (PCD) decoder of GraphicsMagick. In DecodeImage() (coders/pcd.c), the Huffman delta loop advances its output pointer with q++ after every decoded delta and never checks it against the end of the heap-allocated luma/chroma plane buffers. The pointer is repositioned only when a sync marker introduces a new plane/row; between sync markers the run length is bounded solely by the input. A crafted PCD file that positions the pointer near the end of a plane and then supplies a long run of deltas with no intervening sync therefore walks the pointer past the end of the allocation and writes through

[Unknown description]

libjxl: Uninitialized memory read in decoder due to incorrect optimization in patch handling

A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory. This can be done by causing the decoder to reference an outside-image-bound area in a subsequent patches. An incorrect optimization causes the decoder to omit populating those areas.

CVE-2025-32460

GraphicsMagick before 8e56520 has a heap-based buffer over-read in ReadJXLImage in coders/jxl.c, related to an ImportViewPixelArea call.
