encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

CVE-2026-84997

react/http is an event-driven, streaming HTTP client and server implementation for ReactPHP. From 0.6.0 until 1.11.1, React\Http\Io\ChunkedDecoder could enter an infinite loop while processing a malformed Transfer-Encoding: chunked body because handleData required its buffer to shrink on every...

tomcat: Apache Tomcat: Request smuggling vulnerability can lead to denial of service

A flaw was found in Apache Tomcat. This vulnerability, known as HTTP Request/Response Smuggling, occurs when Tomcat processes the transfer-encoding header for an HTTP/1.0 request while operating behind a reverse proxy. A remote attacker could exploit this to cause a denial of service, leading to...

CVE-2026-84997

react/http (ReactPHP) is vulnerable to a denial-of-service via a malformed HTTP chunked body. The ChunkedDecoder enters an infinite loop when it receives either an incomplete terminal-chunk trailer without CRLF or exactly two non-CRLF bytes after a completed non-terminal chunk, because handleData...

libevent: libevent: Multiple HTTP Parser Bugs Enable Request Smuggling

A flaw was found in libevent. The evhttp parser in libevent's http.c component inconsistently handles HTTP Transfer-Encoding headers and chunked framing. This inconsistency allows an unauthenticated remote attacker to desynchronize request boundaries when libevent is used behind a proxy. Successf...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

CVE-2026-81869: Improper Handling of Unicode Encoding

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.10.0 until 1.33.0, the sdk/trace/span.go attribute truncation path can fail to enforce AttributeValueLengthLimit for string and string-slice attributes containing the valid Unicode replacement character U+FFFD...

CVE-2026-70469: Improper Handling of Highly Compressed Data (Data Amplification)

Apache NiFi 2.11.0 disabled support for gzip-encoded HTTP requests for the application REST API and rejected requests that included the standard Content-Encoding header indicating gzip encoding. The framework enforcement filter did not check multiple instances of the Content-Encoding header and d...

CVE-2026-77404: Improper Encoding or Escaping of Output

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, URI.String in uri.go concatenates CertFile, KeyFile, CACertFile, and ServerName values directly into an AMQPS query string instead of encoding them as URL query parameters with url.Values. If an application accepts a TLS asset path...

Linux Distros Unpatched Vulnerability : CVE-2024-14029

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tornado before 6.4.1 ignores duplicate Transfer-Encoding: chunked headers, treating requests as having no message body and parsing the chunked body as a...
