- Summary
- Fix CVE(s): CVE-2026-18924, CVE-2026-80230, CVE-2026-82209
- Details
-
- SECURITY UPDATE: HTTP/2 server push use-after-free
- debian/patches/CVE-2026-18924.patch: make a pushed transfer inherit the parent handle's share in lib/http2.c, so a connection held by a share cannot be freed while the pushed transfer still uses it.
- CVE-2026-18924
- SECURITY UPDATE: public key pinning bypassed when no server certificate
- debian/patches/CVE-2026-80230.patch: in lib/vtls/openssl.c, treat a missing server certificate as acceptable only when no pinned public key is configured, so pinning is still enforced with peer and host verification disabled.
- CVE-2026-80230
- SECURITY UPDATE: cookie for an exact PSL domain kept wildcard scope
- debian/patches/CVE-2026-82209.patch: in lib/cookie.c, clear the tailmatch flag when a cookie's Domain attribute is itself a public suffix, so it becomes host-only instead of being sent to sibling subdomains.
