NPM: Nodemailer addressparser: O(n^2) on comment-joined addresses enables a remote DoS (reachable via mailparser)

NPM: Nodemailer addressparser: On^2 on comment-joined addresses enables a remote DoS reachable via mailparser vulnerability discovered by ? in WordPress Npm nodemailer versions = 9.1.0, = 10.0.4...

Nodemailer addressparser: O(n^2) on comment-joined addresses enables a remote DoS (reachable via mailparser)

Summary nodemailer/lib/addressparser parses one shape of address in On^2 time. A single 640 KB address value blocks the Node.js event loop for roughly 7 seconds. And it is reachable without auth: mailparser feeds inbound email headers straight into this parser, so one crafted email is enough to...

CVE-2026-42772 Potential CPU DoS via O(n^2) Fragment Reassembly in QUIC

Issue summary: The QUIC stream reassembly algorithm performance deteriorates progressively as packets are arriving out of order. The worst case has a quadratic complexity proportional to the number of stream frames kept in the buffer for the received stream data. Impact summary: A remote QUIC pee...

CVE-2026-42772

A flaw in OpenSSL allows a remote attacker to cause a Denial of Service (DoS) by exploiting an inefficient QUIC stream reassembly algorithm. When packets arrive out of order, the software falls back to a head-to-tail linear search for fragments in a doubly-linked list. By manipulating sequence of...

hpack: Unbounded variable integer decoding can cause run-away computation on malformed input

Impact Users of the python-hyper/hpack library, most commonly used as downstream dependency of the python-hyper/h2 library an HTTP/2 client and server implementation. Unbounded variable integer decoding can cause run-away computation on malformed input leading to On^2 runtime, effectively blockin...

DEBIAN-CVE-2026-59980

hpack is an HTTP/2 Header Encoding for Python. Prior to version 4.2.0, unbounded variable integer decoding can cause run-away computation on malformed input leading to On^2 runtime, effectively blocking further processing with large enough unsanitized input. A fix is available in python-hyper/hpa...
