net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME
A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...
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...
