This copy can occur when processing the right or bottom edges of the image, but only when groups are processed in certain order. Groups can be processed out of order in multi-threaded decoding environments with heavy thread load but also with images…
Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Packaging). Supported versions that are affected are 5.5.53 and earlier, 5.6.34 and earlier and 5.7.16 and earlier. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL
