Changes since OpenSSH 9.1
=========================

This release fixes a number of security bugs.

Security
========

This release contains fixes for two security problems and a memory
safety problem. The memory safety problem is not believed to be
exploitable, but we report most network-reachable memory faults as
security bugs.

 * sshd(8): fix a pre-authentication double-free memory fault
   introduced in OpenSSH 9.1. This is not believed to be exploitable,
   and it occurs in the unprivileged pre-auth process that is
   subject to chroot(2) and is further sandboxed on most major
   platforms.

 * ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option
   would ignore its first argument unless it was one of the special
   keywords "any" or "none", causing the permission list to fail open
   if only one permission was specified. bz3515

 * ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs
   options were enabled, and the system/libc resolver did not check
   that names in DNS responses were valid, then use of these options
   could allow an attacker with control of DNS to include invalid
   characters (possibly including wildcards) in names added to
   known_hosts files when they were updated. These names would still
   have to match the CanonicalizePermittedCNAMEs allow-list, so
   practical exploitation appears unlikely.
