    • CVE-2026-33523
  • SECURITY UPDATE: mod_rewrite elevation of privileges via ap_expr in .htaccess
    • debian/patches/CVE-2026-24072.patch: use AP_EXPR_FLAG_RESTRICTED in htaccess context in modules/mappers/mod_rewrite.c and modules/metadata/mod_setenvif.c. mod_proxy_fcgi hunk omitted — ProxyFCGISetEnvIf was added in 2.4.26, after this source.
    • CVE-2026-24072
  • SECURITY UPDATE: mod_auth_digest timing attack allowing Digest auth bypass
    • debian/patches/CVE-2026-33006.patch: use a constant-time comparison helper for nonce hash and digest checks, add VALID_NONCE validation and MD5_DIGEST_LEN length check in get_digest_rec, in modules/aaa/mod_auth_digest.c. Inline ap_crypto_equals_const_time() replaces apr_crypto_equals (added in apr-util 1.6, not in xenial's apr-util 1.5.4); the upstream apr-util version bump and the apr_crypto.h include are omitted accordingly.
