https://matt.ucc.asn.au/dropbear/CHANGES - Security: Fix a use-after-free in X11 forwarding that could possibly lead to memory corruption. This is vulnerable to authenticated users if X11 forwarding is enabled. By default X11 forwarding is not built. In 2026.89 the server is running as the authenticated user for X11 forwarding, in earlier versions it runs as root. This removes X11 "single connection" which has probably never been used. Reported by @peter-pe882f83806dAdded patch to fix build errors which would be introduced by this bump:86baa66fc9Signed-off-by: Bernd Kuhls <bernd@kuhls.net> Signed-off-by: Julien Olivain <ju.o@free.fr> (cherry picked from commit0c8bd5739c) Signed-off-by: Thomas Perale <thomas.perale@mind.be>
