Name of the Vulnerable Software and Affected Versions IBM Watson IoT Message Gateway versions 2.0.0.x, 5.0.0.0, 5.0.0.1, and 5.0.0.2

Description The issue is caused by improper bounds checking when handling a failed HTTP request with specific content in the headers, leading to a buffer overflow. A remote attacker could send a specially crafted HTTP request to overflow a buffer and execute arbitrary code on the system or cause a denial of service.

Recommendations For versions 2.0.0.x, 5.0.0.0, 5.0.0.1, and 5.0.0.2, consider restricting access to the HTTP request handling functionality until a patch is available. As a temporary workaround, avoid using the affected HTTP request handling mechanism to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
