curl: Missing server identity policy enforcement in SSH connection reuse allows host key verification bypass via pool poisoning

Missing server identity policy enforcement in SSH connection reuse allows host key verification bypass via pool poisoning --- Summary sshconfigmatches in lib/url.c decides whether an existing SSH connection can be reused by a new transfer handle. It checks client key paths rsa, rsapub but never...

curl: Use-After-Free race condition in url_move_hostname() via shared connection pool

Summary: In lib/url.c, urlconnreuseadjust calls urlmovehostname which frees conn-host.rawalloc and conn-host.encalloc via Curlsafefree and Curlfreeidnconvertedhostname after Curlcpoolfind has already released the connection pool lock. A second thread doing a concurrent pool lookup still holds tha...
