crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

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...

bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...

bind: bind9: Incorrect acceptance of NSEC3 records

BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses...

Important: Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update

bind: bind9: Key Record using PRIVATEDNS algorithm may lead to exit

If BIND encounters a particular invalid data structure in a DNS record, it will accept the invalid data, and may subsequently abort and exit. BIND will first need to store a DNS record for a key KEY, DNSKEY, etc.. That key must specify a PRIVATEDNS algorithm 253, and in the algorithm identifier,...

bind: bind9: Potential memory usage beyond configured limits

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...
