AZL-98616 CVE-2026-56862 affecting package golang 1.27.1-1

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely...

Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures...

UBUNTU-CVE-2026-56858

Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS...

CVE-2026-56862 Limit handshake messages we are willing to accept post-handshake in crypto/tls

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely...

CVE-2026-56860

The net/url package in golang is vulnerable to a Denial of Service (DoS) due to quadratic time complexity during path resolution. When resolving relative paths containing parent directory (..) segments, the system previously performed string conversions and buffer rewrites at each step, leading t...

CVE-2026-56862

The golang programming language is vulnerable to a Denial of Service (DoS) attack within its crypto/tls package. The vulnerability is caused by the system treating handshake messages, specifically KeyUpdate , as state-advancing even before a handshake has been completed. This allows a malicious c...

CVE-2026-56853 Apply ReadHeaderTimeout when doing unencrypted HTTP/2 check in net/http

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this...

CVE-2026-56860 Avoid quadratic complexity in resolvePath in net/url

Previously, resolving relative paths containing parent directory '..' segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking f...
