- Update to openssh 9.3p2 (bsc#1213504, CVE-2023-38408):
  Security
  ========
  Fix CVE-2023-38408 - a condition where specific libaries loaded via
  ssh-agent(1)'s PKCS#11 support could be abused to achieve remote
  code execution via a forwarded agent socket if the following
  conditions are met:
  * Exploitation requires the presence of specific libraries on
    the victim system.
  * Remote exploitation requires that the agent was forwarded
    to an attacker-controlled system.
  Exploitation can also be prevented by starting ssh-agent(1) with an
  empty PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring
  an allowlist that contains only specific provider libraries.
  This vulnerability was discovered and demonstrated to be exploitable
  by the Qualys Security Advisory team. 
 
  In addition to removing the main precondition for exploitation,
  this release removes the ability for remote ssh-agent(1) clients
  to load PKCS#11 modules by default (see below).
  Potentially-incompatible changes
  --------------------------------
   * ssh-agent(8): the agent will now refuse requests to load PKCS#11
     modules issued by remote clients by default. A flag has been added
     to restore the previous behaviour "-Oallow-remote-pkcs11".
     Note that ssh-agent(8) depends on the SSH client to identify
     requests that are remote. The OpenSSH >=8.9 ssh(1) client does
     this, but forwarding access to an agent socket using other tools
     may circumvent this restriction.
