- Details

- SECURITY UPDATE: use-after-free in the ssh client when a remote
forwarding is added over the multiplexing socket
- debian/patches/CVE-2026-73282.patch: pass a heap-allocated index instead of a pointer into options.remote_forwards[] to ssh_confirm_remote_forward() in ssh.c, so a concurrent add_remote_forward() reallocation cannot leave the pending global request confirmation holding a dangling pointer.
- CVE-2026-73282
- SECURITY UPDATE: authorized_keys restrict keyword did not cover
tunnel forwarding
- debian/patches/CVE-2026-73283.patch: also reject tunnel device forwarding in server_request_tun() (serverloop.c) when the authenticating key carries the restrict option.
