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,...

golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Unauthorized command execution via discarded SSH permissions

A flaw was found in golang.org/x/crypto/ssh. A remote attacker could exploit this vulnerability when an SSH server authentication callback returned a PartialSuccessError with non-nil permissions. This flaw caused these permissions to be silently discarded, potentially bypassing certificate...

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,...

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,...

Improper Certificate Validation

golang.org/x/crypto is vulnerable to Improper Certificate Validation. The vulnerability is due to the failure to verify the revocation status of a CA's associated SignatureKey, where only the primary key was checked for revocation. This allows an attacker to exploit a revoked CA SignatureKey that...

UBUNTU-CVE-2026-7511

PKCS7verify signer confusion allows forged signatures, where the signer associated with a signature is not correctly bound, permitting a forged signature to be accepted...

golang.org/x/crypto vulnerable to invoking bypass of certificate restrictions

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError...

UBUNTU-CVE-2026-6291

Bleichenbacher padding oracle in PKCS7 KTRI decryption. When decrypting PKCS7 EnvelopedData using RSA PKCS1 v1.5 key transport, wolfSSL returned distinguishable error codes depending on whether RSA padding validation failed versus whether the decrypted content was malformed. An attacker able to...

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...
