    Package        : ksh
    Version        : 93u+20120801-3.1+deb9u1
    CVE ID         : CVE-2019-14868
    
    A flaw was found in the way it evaluates certain
    environment variables. An attacker could use this
    flaw to override or bypass environment restrictions
    to execute shell commands. Services and
    applications that allow remote unauthenticated
    attackers to provide one of those environment
    variables could allow them to exploit this issue
    remotely.
    
    For Debian 9 stretch, this problem has been fixed in version
    93u+20120801-3.1+deb9u1.
    
    We recommend that you upgrade your ksh packages.
    
    For the detailed security status of ksh please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/ksh
