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...
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...
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...
rsync: rsync: Unauthorized File Access via Symlink Module Root
A flaw was found in rsync. This path traversal vulnerability allows remote clients to access files outside the intended module root. This occurs when the use chroot option is disabled and the module root path, or a component of it, is a symbolic link. The rsync daemon fails to resolve symlinks...
rsync: rsync: Arbitrary file deletion via malicious file list
