IBM Informix Dynamic Server is prone to an overflow condition. The program fails to properly sanitize user-supplied input resulting in a stack-based buffer overflow. With specially crafted lengthy DBINFO keyword arguments in an SQL statement, a remote attacker can potentially execute arbitrary code.
Upgrade to version 10.00.xC10, 11.10.xC3, 11.50.xC3 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
