PYSEC-2026-3435 python-zeroconf: Unbounded TC-deferred queue allows LAN-local memory exhaustion via spoofed-source flood

Impact AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query in self.deferredaddr and armed a per-addr timer in self.timersaddr that flushed the reassembled query within 500 ms RFC 6762 §18.5. Neither the per-addr list nor the number of distinct addr keys was capped, and...

zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion

zeroconf has unbounded recursion in DNS compression-pointer decoder that allows LAN-local denial of service

ImpactDNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer RFC 1035 §4.1.4. Pointer cycles and label counts were capped, but the chain length of unique forward pointers was not. A single 3 kB mDNS packet carrying 1500 chained pointers drives the recursion past CPython's...

PYSEC-2026-3439 zeroconf has unbounded DNS record cache that allows LAN-local memory exhaustion via multicast flood

Impact DNSCache.asyncadd inserted every response record into cache, expirations, expireheap, and servicecache with no cap on entry count. The only pre-existing protection was a PTR TTL floor DNSPTRMINTTL = 1125 s, RFC 6762 §10, which actually prolonged attacker-injected records, and a periodic...

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...

CVE-2026-15548

A security vulnerability has been detected in Shibby Tomato up to 1.28.0000. This vulnerability affects the function sub407220 of the file /usr/sbin/httpd of the component DNS List Rendering. The manipulation leads to stack-based buffer overflow. The attack is possible to be carried out remotely...

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...
