CVE-2026-111438 check_hba_replication 认证与访问控制绕过
在 openGauss-server 的 src/common/backend/libpq/hba.cpp 中，复制连接认证存在访问控制绕过。hbagetauthmethod 在处理 HADR/SW 复制发送方时，不要求 isnodeinternalconnection，直接调用 checkhbareplication。checkhbareplication 仅按 replication 标记做弱匹配，缺少普通 checkhba 中的远程 trust 禁止等完整校验。因此，非内部网络的 HADR/SW 复制连接可绕过内部连接限制和完整 pghba...

389-ds-base: 389-ds-base: pre-authentication stack buffer overflow in get_ruvelement_from_berval() via unbounded replica ID parsing
A stack buffer overflow flaw was found in 389 Directory Server 389-ds-base. The getruvelementfromberval function in repl5ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP...
