CVE-2017-10788 is a critical-severity flaw (CVSS 9.8) affecting dbd-mysql. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
