Fix DoS vulnerability based on unbounded TCP buffering. In Application.__handle_recv(), the next part of the TCP exchange is received and queued to the io.BytesIO stream. This update fixes: - Interrupt receiving message after exceeding maximum length - Only export buffer content once receiving process has ended Upstream: latchset/kdcproxy@c767536 Generated-By: glm-5.1 Co-Authored-By: hudeng <hudeng@deepin.org>
Unauthenticated SSRF via Realm-Controlled DNS. Allowing DNS discovery for any requested realm created a server-side request forgery vulnerability. This update: - Makes use_dns apply only to realms declared in configuration - Adds wildcard support for realm section names - Adds dns_realm_discovery parameter for unsafe behavior Upstream: latchset/kdcproxy@1773f28 Generated-By: glm-5.1 Co-Authored-By: hudeng <hudeng@deepin.org>
