A vulnerability has been identified in SIMATIC S7-PLCSIM Advanced All versions. Affected devices do not properly handle high-volume multicast network traffic, which can exhaust available memory resources in the affected application. This could allow an unauthenticated attacker on the local networ...
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...
zeroconf has unbounded DNS record cache that allows LAN-local memory exhaustion via multicast flood
ImpactDNSCache.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...
PYSEC-2026-3437 zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion
Impact DNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dict keyed by strsys.excinfo1. The seven IncomingDecodeError messages raised from readname / decodelabelsatoffset RFC 6762 §18 name-decoding error paths all embed self.source — the...

Impact AsyncListener.handle query or defer 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...
