Description

Dmitri Lenev reports a privilege escalation in MySQL. MySQL evaluates arguments of suid routines in the security context of the routine's definer instead of the routine's caller, which allows remote and local authenticated users to gain privileges through a routine that has been made available using GRANT EXECUTE.
