Summary
Fix CVE(s): CVE-2025-49630
Details
  • SECURITY UPDATE: DoS in mod_proxy_http2 via missing Host header with ProxyPreserveHost
    • debian/patches/CVE-2025-49630.patch: in open_stream() in modules/http2/h2_proxy_session.c, when preserve_host is on and the client request has no Host header, fall back to r->server->server_hostname and add it to the request headers so a NULL authority no longer trips an assertion in the h2 proxy path. Backported from httpd commit 88304321841a2fe8bd5eacc70e69418b0b545ca5 (SVN r1927044, 2.4.x branch), plus adapted regression test from SVN r1934478 (test/modules/http2/test_600_h2proxy.py).
