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...

netty-resolver-dns: Netty DNS resolver: DNS Cache Poisoning via predictable transaction IDs

A flaw was found in Netty's DNS resolver component. This vulnerability arises from the use of a predictable pseudo-random number generator PRNG for DNS transaction IDs and a static User Datagram Protocol UDP source port. This combination significantly reduces the randomness of DNS queries, making...

PYSEC-2026-3570 Flyto2 Core: ${env.VAR} interpolation reads any env secret despite env.get being denylisted

Summary The capability policy denies the env.get and env.loaddotenv modules by default, with the stated reason that they read arbitrary host environment variables API keys, DSNs and are a secret-exfil risk. But the workflow engine's variable resolver expands $env.VAR for any environment variable...
