Fix of 6 CVEs
* SECURITY UPDATE: potential SSRF in mod_rewrite via RewriteRule substitutions that produce a scheme-like target - debian/patches/CVE-2024-39573.patch: add the previously stripped per-directory prefix, or an implicit '/' root prefix, to the substituted URI before the query args are split in apply_rewrite_rule() in modules/mappers/mod_rewrite.c; otherwise a rule such as "RewriteRule ^/some/path(.*) $1" turns "/some/pathscheme:..." into the fully qualified URL "scheme:...", which mod_proxy then handles. Upstream fix 93aec0e3ca451bcc97f6d91c14d5399d13a73365 (SVN r1918600). - CVE-2024-39573 * SECURITY UPDATE: insufficient escaping of mod_ssl variables written to the log by CustomLog - debian/patches/CVE-2024-47252.patch: pass the results of ssl_var_log_handler_c() and ssl_var_log_handler_x() through ap_escape_logitem() in modules/ssl/ssl_engine_vars.c, so an untrusted TLS client can no longer insert escape characters into log files through the %{varname}c and %{varname}x formats logging mod_ssl variables such as SSL_TLS_SNI. Upstream fix c01e60707048be14a510f0a92128a5227923215c (SVN r1927042). - CVE-2024-47252 * SECURITY UPDATE: access control bypass by trusted clients through TLS 1.3 session resumption in mod_ssl - debian/patches/CVE-2025-23048.patch: move the ssl_server_compatible() check in ssl_hook_ReadReq() in modules/ssl/ssl_engine_kernel.c out of the SNI-present branch, so the handshake virtual host and the request virtual host are compared even when the client sent no SNI
