NotEnough

Huffman table hacking tool This tool calculates tricky canonical huffman histogram, which is able to trigger OOB Out Of Band write for vulnerable libwebp library i.e. libwebp = 1.3.1. This vulnerability is known as CVE-2023-4863 or CVE-2023-41064. We can overflow the pre-allocated huffman table b...

CVE-2026-46603

A flaw was found in golang.org/x/image/vp8l. A remote attacker can cause a denial of service by providing a specially crafted VP8L image. This image, containing many unused Huffman tree groups, leads to excessive memory allocation during VP8L decoding, resulting in memory exhaustion. Mitigation...

Astra Linux – Vulnerability in libstb

It was discovered that stbimage.h v2.27 contains a heap-based use-after-free issue due to the stbijpeghuffdecode function...

Astra Linux – Vulnerability in grub2

A heap out-of-bounds write may occur during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. The impacts on confidentiality, integrity, and availability are considered low, as it is very complex for an attacker to control the encoding and...

Astra Linux – Vulnerability in gst-plugins-bad1.0

GStreamer JPEG Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability, but the attack vectors may va...

CVE-2026-55586

SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, a crafted CHM file can supply malformed LZX Huffman code lengths to makedecodetable in ext/CHMLib/lzx.c. In the long-code branch, the function writes new internal nodes through nextsymbol before validating that the canonical...

CVE-2026-77118 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...
