Replication: mysqlbinlog --read-from-remote-server log1 log2 was opening a new connection for
log2
without freeing the connection used forlog1
. Thanks to Laurynas Biveinis for the contribution. (Bug #81675, Bug #23540182)-
For mysqld_safe, the argument to
--malloc-lib
now must be one of the directories/usr/lib
,/usr/lib64
,/usr/lib/i386-linux-gnu
, or/usr/lib/x86_64-linux-gnu
. In addition, the--mysqld
and--mysqld-version
options are accepted only on the command line, not in option files. (Bug #24464380)References: See also: Bug #24619033, Bug #82920.
It was possible to write log files ending with
.ini
or.cnf
that later could be parsed as option files. The general query log and slow query log can no longer be written to a file ending with.ini
or.cnf
. (Bug #24388753)Privilege escalation was possible by exploiting the way
REPAIR TABLE
used temporary files. (Bug #24388746)Certain internal character-handling functions could fail to handle a too-large character and cause a server exit. (Bug #23296299)
A blank server name in
CREATE SERVER
statements produced a server exit rather than an error. (Bug #23295288)The optimizer failed to check a function return value for an area calculation, leading to a server exit. (Bug #23280059)
A prepared statement that used a parameter in the select list of a derived table that was part of a join could cause a server exit. (Bug #22392374, Bug #24380263)
MEDIUMINT
columns used in operations with long integer values could result in buffer overflow. (Bug #19984392)EINTR
handling in the client library has been fixed so that interrupted read and write calls are retried. Previously,EINTR
was ignored. (Bug #82019, Bug #23703570)
