UBUNTU: 2019:3923-1 Critical: OpenSSL-Crypto1 Service Interruption

This update for openssh-openssl1 fixes the following issues: These security issues were fixed: - CVE-2016-10708: Prevent NULL pointer dereference via an out-of-sequence NEWKEYS message allowed remote attackers to cause a denial of service (bsc#1076957). - CVE-2017-15906: The process_open function did not properly prevent write operations in readonly mode, which allowed attackers to create zero-length files (bsc#1065000). - CVE-2016-10012: The shared memory manager (associated with pre-authentication compression) did not ensure that a bounds check is enforced by all compilers, which might have allowed local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures (bsc#1016370).
