   An update that fixes two vulnerabilities is now available.

Description:

   This update for perl-DBD-mysql fixes the following issues:

   - CVE-2017-10789: The DBD::mysql module when with mysql_ssl=1 setting
     enabled, means that SSL is optional (even though this setting's
     documentation has a \"your communication with the server will be
     encrypted\" statement), which could lead man-in-the-middle attackers to
     spoof servers via a cleartext-downgrade attack, a related issue to
     CVE-2015-3152. (bsc#1047059)
   - CVE-2017-10788: 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. (bsc#1047095)
