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...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the HostnameError.Error function. This flaw, caused by unbounded string concatenation, leads to excessive resource...

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...

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...

crypto/x509: Incorrect enforcement of email constraints in crypto/x509

A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly...
