curl: Use-After-Free in SMB connection reuse (req->path dangling pointer after needle destruction)

Summary A heap-use-after-free occurs in smbsendopen at lib/smb.c when curl processes two SMB URLs targeting the same host. The function smbparseurlpath sets req-path as a non-owning pointer into smbc-share connection-owned memory. During connection reuse, the needle connection is freed via...
