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...

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...

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...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...
