GHSA-7Q85-XJ36-VMFC adm-zip: Uncontrolled memory allocation via the declared uncompressed size (DoS)

Summary adm-zip allocates an entry's output buffer from the declared uncompressed size central-directory size field before validating it against the actual data. A tiny crafted ZIP that declares a huge uncompressed size forces a multi-gigabyte allocation from a few bytes. Impact On adm-zip 0.5.17...

CVE-2026-84384 libheif: brotli/zlib decompression paths lack output-size limits, allowing decompression-bomb OOM/DoS

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.2, crafted HEIF or AVIF mime metadata and unci image data can cause decompressbrotli and doinflate to grow accumulated output without an effective size limit or MemoryHandle accounting. The brotli path has no outpu...

libheif (a HEIF and AVIF file format decoder/encoder) is affected by a decompression-bomb OOM/DoS vulnerability in versions 1.19.0 through 1.23.1 . Crafted HEIF or AVIF files with malicious mime metadata and unci image data cause decompress_brotli() and do_inflate() to grow accumulated output wit...

CVE-2026-93488 Io.netty/netty-codec-http: netty: denial of service via unbounded concurrent spdy streams

A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAXVALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYNSTREAM...
