net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

net/mail: golang: Go net/mail: Denial of Service via crafted email inputs

A flaw was found in the net/mail package of the Go programming language. An attacker could provide specially crafted inputs to the ParseAddress, ParseAddressList, or ParseDate functions. This could lead to excessive consumption of CPU and memory resources, resulting in a Denial of Service DoS for...

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...

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...

qt: Qt: Denial of Service via out-of-bounds read in text codec handling

A flaw was found in Qt, a popular software development framework. This vulnerability, an out-of-bounds read, occurs in the QTextCodec::codecForName function when it processes specially crafted input that is not properly terminated. An attacker could exploit this to cause the application to select...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability fro...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...

net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

net/mail: golang: net/mail: Denial of Service via pathological email address parsing

A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...

CVE-2026-87827
