"The version of Oracle Secure Global Desktop installed on the remote
host is 5.3 and is missing a security patch from the January 2018
Critical Patch Update (CPU). It is, therefore, affected by multiple
vulnerabilities:

  - The included OpenSSL library has a off-by-one out-of-bounds read
    flaw within the X509v3_addr_get_afi() function of
    crypto/x509v3/v3_addr.c when handling the IPAddressFamily
    extension of X.509 certificates. A content-dependent attacker,
    with a specially crafted request, could potentially read limited
    memory information. (CVE-2017-3735)

  - The included OpenSSL library has a carry propagating flaw within
    the bn_sqrx8x_internal() function in crypto/bn/asm/x86_64-mont5.pl
    when handling RSA / DSA encryption. A content-dependent attacker,
    with a specially crafted request, could potentially determine the
    private key. (CVE-2017-3736)

  - The included Apache Log4j contains a flaw due to improper
    validation of log events before deserializing. A remote attacker,
    with a specially crafted log event, could potentially execute
    arbitrary script code. (CVE-2017-5645)");
