Oracle MySQL Client yaSSL Certificate Decode Buffer Overflow Vulnerability

MySQL is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer.

Attackers can exploit this issue to execute arbitrary code within the context of the application. Failed attacks may cause a denial-of-service condition.

Versions prior to MySQL 5.5.39 and 5.6.20 are vulnerable.
