Egress Policy Bypass via DNS over TCP in Harden-Runner (Community Tier)

Summary A vulnerability exists in the Community Tier of Harden-Runner that allows bypassing the egress-policy: block network restriction using DNS queries over TCP. Harden-Runner enforces egress policies on GitHub runners by filtering outbound connections at the network layer. When egress-policy:...

CVE-2025-61430

Improper handling of DNS over TCP in Simple DNS Plus v9 allows a remote attacker with querying access to the DNS server to cause the server to return request payloads from other clients. This happens when the TCP length prefix is malformed len differs from actual packet len, and due to a...

glibc: Stack read overflow in getaddrinfo in no-aaaa mode

A flaw was found in glibc. When the getaddrinfo function is called with the AFUNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data...
