"The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in
the USN-5344-1 advisory.

  - The DBD::mysql module before 4.039 for Perl, when using server-side prepared statement support, allows
    attackers to cause a denial of service (out-of-bounds read) via vectors involving an unaligned number of
    placeholders in WHERE condition and output fields in SELECT expression. (CVE-2016-1249)

  - There is a vulnerability of type use-after-free affecting DBD::mysql (aka DBD-mysql or the Database
    Interface (DBI) MySQL driver for Perl) 3.x and 4.x before 4.041 when used with mysql_server_prepare=1.
    (CVE-2016-1251)

  - The DBD::mysql module through 4.043 for Perl allows remote attackers to cause a denial of service (use-
    after-free and application crash) or possibly have unspecified other impact by triggering (1) certain
    error responses from a MySQL server or (2) a loss of a network connection to a MySQL server. The use-
    after-free defect was introduced by relying on incorrect Oracle mysql_stmt_close documentation and code
    examples. (CVE-2017-10788)

  - The DBD::mysql module through 4.043 for Perl uses the mysql_ssl=1 setting to mean that SSL is optional
    (even though this setting's documentation has a your communication with the server will be encrypted
    statement), which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, a
    related issue to CVE-2015-3152. (CVE-2017-10789)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
