Multiple vulnerabilities have been identified in MySQL

[equens]

Multiple vulnerabilities have been identified in MySQL, which could be exploited by attackers to compromise a vulnerable system or gain knowledge of sensitive information.

The first flaw is due to a buffer overflow error in the "sql_base.cc" script that does not properly handle specially crafted "COM_TABLE_DUMP" packets, which could be exploited by authenticated attackers to execute arbitrary commands.

The second issue is due to an input validation error in the "sql_parse.cc" file that fails to properly validate "COM_TABLE_DUMP" packets, which could be exploited by attackers to cause portions of the memory to be disclosed in error messages.

The third vulnerability is due to an input validation error in the "sql_parse.cc" script that fails to properly handle malformed login packets, which could be exploited by attackers to cause portions of the memory to be disclosed in error messages.

Upgrading to 4.1.19 would also be a solution?
