Name of the Vulnerable Software and Affected Versions Inbit Messenger versions 4.6.0 through 4.9.0

Description A remote stack-based buffer overflow exists in Inbit Messenger that allows unauthenticated attackers to execute arbitrary code. This is achieved by sending malformed network packets to the messenger's network handler. Successful exploitation allows attackers to overwrite the Structured Exception Handler (SEH) and execute shellcode on vulnerable Windows systems.

Recommendations Update Inbit Messenger to a version later than 4.9.0.
