Discussion

OpenLDAP Server Kerveros 4 Bind Request Buffer Overflow Vulnerability

OpenLDAP server is prone to a remote stack-based buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied input prior to copying it to an insufficiently sized memory buffer.

Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the affected application, facilitating the remote compromise of affected computers.

Note that the vulnerable code is not enabled by default; its use has been deprecated for a significant period of time.
