undici: undici: Denial of Service via unhandled error in WebSocket permessage-deflate decompression

A flaw was found in undici. A remote, unauthenticated attacker can trigger a Denial of Service DoS by sending a specially crafted compressed WebSocket payload. When this payload exceeds the 128 MiB decompressed-payload limit and contains a malformed DEFLATE byte, it causes an unhandled error in t...

SoupWebsocketExtensionDeflate: libsoup: libsoup: WebSocket permessage-deflate Unbounded Decompression Remote Denial of Service

A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification in the inflate payload processing path. An attacker can exhaust memory or trigger severe garbage-collection pressure by supplying a Smart Health Card JWT with a zip":"DEF"...

HAPI FHIR: SHCParser DEFLATE infinite loop causes denial of service

A malformed Smart Health Card SHC JWT with zip: "DEF" and an empty or truncated DEFLATE payload causes SHCParser.inflate to loop forever. This allows an attacker who can submit SHC content for validation to pin a JVM worker thread indefinitely, causing denial of service...

Astra Linux – Vulnerability in zlib, libz-mingw-w64

Zlib versions up to 1.2.12 have a heap-based buffer over-read or buffer overflow issue in the inflate function within inflate.c, due to a large gzip header extra field. NOTE: Only applications that call inflateGetHeader are affected. Some common applications bundle the affected Zlib source code,...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU-built-in VNC server during the processing of ClientCutText messages. A incorrect exit condition may lead to an infinite loop when inflating a zlib buffer controlled by an attacker in the inflatebuffer function. This could allow a remotely authenticated client, wh...

Astra Linux – Vulnerability in Jetty9

In Eclipse Jetty versions 9.4.0 to 9.4.56, a buffer can be released incorrectly when encountering a gzip error during the inflation of a request body. This can lead to corrupted data and/or unintentional sharing of data between requests...

Astra Linux – Vulnerability in gst-plugins-good1.0

DOS: Potential heap overwrite in qtdemux using zlib decompression. Integer overflow in the qtdemux element within the qtdemuxinflate function can lead to a segfault, or it may cause a heap overwrite, depending on the libc and operating system. Depending on the libc used and the underlying operati...

CVE-2026-85024

undici bundles a WebSocket client whose permessage-deflate size-limit cleanup removes all listeners from the internal zlib inflate stream, including its error listener, while that stream can still emit. When a remote peer sends a compressed payload that crosses the built-in 128 MiB...
