* SECURITY UPDATE: buffer over-read in mod_ssl OCSP requests - debian/patches/CVE-2026-44185.patch: in send_request() in modules/ssl/ssl_util_ocsp.c, advance the write pointer by the number of bytes actually sent instead of the total remaining length so a short write to an attacker controlled OCSP responder can no longer read past the end of the stack buffer.
