"The version of HPE Intelligent Management Center (iMC) PLAT installed
on the remote host is prior to 7.3 E0605P06. It is, therefore,
affected by multiple vulnerabilities :

  - A stack-based buffer overflow condition exists in the dbman
    process due to improper validation of the length of user-supplied
    data when decrypting a request message. An unauthenticated,
    remote attacker can exploit this, via a specially crafted
    request, to cause a denial of service condition or the execution
    of arbitrary code. (CVE-2018-7114)

  - A stack-based buffer overflow condition exists in the dbman
    process due to improper validation of the length of user-supplied
    data when writing the data to a debug log. An unauthenticated,
    remote attacker can exploit this, via a specially crafted
    request, to cause a denial of service condition or the execution
    of arbitrary code. (CVE-2018-7115)

  - A denial of service (DoS) vulnerability exists in the dbman
    process due to improper validation of the length of user-supplied
    data when processing an AsnPlatManualRestoreReqContent ASN.1
    message. An unauthenticated, remote attacker can exploit this,
    via a specially crafted request, to cause the process to
    terminate and restart. (CVE-2018-7116)

Note that Intelligent Management Center (iMC) is an HPE product;
however, it is branded as H3C.");
