Description Andrej Nemec 2016-11-16 09:38:06 UTC 
A vulnerability was discovered in perl-DBD-MySQL that can lead to an out-of-bounds read when using server side prepared statements with an unaligned number of placeholders in WHERE condition and output fields in SELECT expression.

This problem is only exposed when the user uses server-side prepared statement support, which is NOT default behavior and was turned off back for all drivers per MySQL AB decision in 2006 due to issues with server-side prepared statements in the server. The behavior of the driver is normally emulated.
