[slackware-security]  openssh (SSA:2016-358-02)

New openssh packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1,
14.2, and -current to fix security issues.

Here are the details from the Slackware 14.2 ChangeLog:
patches/packages/openssh-7.4p1-i586-1_slack14.2.txz:  Upgraded.
  This is primarily a bugfix release, and also addresses security issues.
  ssh-agent(1): Will now refuse to load PKCS#11 modules from paths outside
    a trusted whitelist.
  sshd(8): When privilege separation is disabled, forwarded Unix-domain
    sockets would be created by sshd(8) with the privileges of 'root'.
  sshd(8): Avoid theoretical leak of host private key material to
    privilege-separated child processes via realloc().
  sshd(8): The shared memory manager used by pre-authentication compression
    support had a bounds checks that could be elided by some optimising
    compilers to potentially allow attacks against the privileged monitor.
    process from the sandboxed privilege-separation process.
  sshd(8): Validate address ranges for AllowUser and DenyUsers directives at
    configuration load time and refuse to accept invalid ones.  It was
    previously possible to specify invalid CIDR address ranges
    (e.g. user@ and these would always match, possibly resulting
    in granting access where it was not intended.
