The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: crypto/krb5, rxrpc: Fix lack of pre- decrypt/pre-verify length checks Change the krb5 crypto...

CVE-2026-64208 crypto/krb5, rxrpc: Fix lack of pre-decrypt/pre-verify length checks

In the Linux kernel, the following vulnerability has been resolved: crypto/krb5, rxrpc: Fix lack of pre-decrypt/pre-verify length checks Change the krb5 crypto library to provide facilities to precheck the length of the message about to be decrypted or verified. Fix AFRXRPC to make use of this to...

golang.org/x/crypto/ssh: golang: golang.org/x/crypto/ssh: Denial of Service via crafted SSH certificate

A flaw was found in golang.org/x/crypto/ssh. SSH servers configured to use CertChecker as a public key callback, without explicitly setting IsUserAuthority or IsHostAuthority, are vulnerable. A remote attacker can exploit this by presenting a specially crafted certificate, causing the server to...

ROOT-APP-GOBINARY-CVE-2025-58181 CVE-2025-58181 in rootio-golang.org/x/crypto - Patched by Root

Root has patched CVE-2025-58181 in the rootio-golang.org/x/crypto package for Root:Go. Multiple fixed versions available...

GHSA-RM3J-F69W-WQMQ golang.org/x/crypto vulnerable to infinite loop on large channel writes

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation...

GHSA-W879-237Q-WC7R golang.org/x/crypto: Invoking pathological RSA/DSA parameters may cause DoS

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

GHSA-Q4H4-GMJ2-QVW2 golang.org/x/crypto: Invoking byte arithmetic causes underflow and panic

An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs...

GHSA-JPPX-RXG9-JMRX golang.org/x/crypto doesn't enforce invoking key constraints

The in-memory keyring returned by NewKeyring silently accepted keys with the ConfirmBeforeUse constraint but never enforced it. The key would sign without any confirmation prompt, with no indication to the caller that the constraint was not in effect. NewKeyring now returns an error when...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

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

MGASA-2026-0179 Updated golang-x-crypto & golang-x-sys-devel packages fix security vulnerability

fixes a protocol weakness in the golang.org/x/crypto/ssh package that allowed a MITM attacker to compromise the integrity of the secure channel before it was established, allowing them to prevent transmission of a number of messages immediately after the secure channel was established without...

golang.org/x/crypto/ssh/knownhosts: golang: golang.org/x/crypto/ssh/knownhosts: Revocation bypass via unchecked SignatureKey

A flaw was found in golang.org/x/crypto/ssh/knownhosts. This vulnerability occurs because the system did not correctly check for the revocation status of a SignatureKey belonging to a Certificate Authority CA. A remote attacker could potentially exploit this by presenting a revoked key, leading t...
