The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the ALTER TABLE implementation. A remote attacker can execute arbitrary code on the target system, as demonstrated by an ORDER BY clause that belongs to a compound SELECT statement.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
