Who is Vulnerable?
Vulnerability Description There is a buffer overflow vulnerability exists in IBM Lotus Notes. The vulnerability is due to a boundary error within the Lotus 1-2-3 file viewer. A remote attacker could leverage this vulnerability by enticing a target user to view the maliciously crafted email attachment. Successful attack could allow for arbitrary code injection and execution with the privileges of the currently logged on user. In an attack case where code injection is not successful, all instances of the vulnerable IBM Lotus Notes application will terminate. In a more sophisticated attack scenario where code injection is successful, the behavior of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user. The affected application would also most likely stop functioning as a result of such an attack.
