"The version of Oracle Secure Global Desktop installed on the remote
host is version 4.63 / 4.71 / 5.2 and is missing a security patch from
the January 2016 Critical Patch Update (CPU). It is, therefore,
affected by the following vulnerabilities :

  - A flaw exists in the bundled version of Apache HTTP
    Server in the chunked transfer coding implementation due
    to a failure to properly parse chunk headers. A remote
    attacker can exploit this to conduct HTTP request
    smuggling attacks. (CVE-2015-3183)

  - A man-in-the-middle vulnerability, known as Logjam,
    exists due to a flaw in the SSL/TLS protocol. A remote
    attacker can exploit this flaw to downgrade connections
    using ephemeral Diffie-Hellman key exchange to 512-bit
    export-grade cryptography. (CVE-2015-4000)

  - An unspecified flaw exists in the SGD Core subcomponent
    that allows a remote attacker to cause a denial of
    service condition. (CVE-2016-0501)");
