IBM Informix Dynamic Server 14.10.x < 14.10.xC5 Buffer Overflow (6448568)

medium Nessus Plugin ID 149349

Language:

Synopsis

A database server installed on the remote host is affected by a buffer overflow condition.

Description

The version of IBM Informix Dynamic Server installed on the remote is 14.10.x prior to 14.10.xC5. It is, therefore, affected by a buffer overflow, caused by improper bounds checking. A local privileged user could overflow a buffer and execute arbitrary code on the system or cause a denial of service (DoS) condition.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to IBM Informix Dynamic Server to the fixed version mentioned in the vendor advisory.
