-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
systems with vulnerable installations of IBM's Informix Dynamic Server.
User interaction is not required to exploit this vulnerability.
Authentication is required in that an attacker must have database
connection priviliges.
The specific flaw exists in the oninit.exe process that listens by
default on TCP port 1526. During authentication, the process does not
validate the length of the DBPATH variable. An attacker can provide a
overly long variable name and overflow a global buffer, overwriting
function pointers leading to arbitrary code execution.
-- Vendor Response:
IBM has issued an update to correct this vulnerability. More
