Summary
Fix CVE(s): CVE-2026-49975
Details
  • SECURITY UPDATE: memory allocation with excessive size value (DoS) in mod_http2 HTTP/2 cookie header merging
    • debian/patches/CVE-2026-49975.patch: count merged cookie headers as an add so they keep counting against LimitRequestFields, and ignore duplicate empty cookie headers, in req_add_header() in modules/http2/h2_util.c; otherwise repeated HTTP/2 cookie headers merge into one growing value without tripping the LimitRequestFields guard, letting a single stream drive unbounded memory allocation. Upstream fix 35c6e405390ed361189a82acd96675401ea5947c (SVN r1934882).
