EulerOS installation on the remote host is affected by the following
vulnerability :
- The shared memory manager (associated with
pre-authentication compression) in sshd in OpenSSH
before 7.4 does not ensure that a bounds check is
enforced by all compilers, which might allows local
users to gain privileges by leveraging access to a
sandboxed privilege-separation process, related to the
m_zback and m_zlib data structures.(CVE-2016-10012)
