Description:
Multiple vulnerabilities have been reported in IBM Lotus Notes, which can be exploited by malicious, local users to gain knowledge of potentially sensitive information and by malicious people to bypass certain security mechanisms or compromise a user's system.
1) Errors within various third-party file viewers (mifsr.dll, awsr.dll, kpagrdr.dll, exesr.dll, rtfsr.dll, mwsr.dll, exesr.dll, wp6sr.dll, and lasr.dll) can be exploited to cause buffer overflows by tricking a user into viewing a specially crafted attachment.
Successful exploitation may allow execution of arbitrary code.
2) A boundary error when parsing HTML messages in nnotes.dll can be exploited to cause a buffer overflow when a user acts upon a malicious HTML message (e.g. replying, forwarding, or copying it to the clipboard).
Successful exploitation may allow execution of arbitrary code.
3) An error in the ECL (Execution Control List) mechanism may result in attachments being executed automatically instead of displaying the Execution Security Alert when handling Notes database (.nsf) and Notes template (.ntf) attachments.
4) Insecure permissions on shared memory allows any local user to access memory containing other users' data.
5) An error in the Lotus Notes client when processing specially-crafted SMTP responses can be exploited to crash the client or execute arbitrary code.
Solution:
Update to version 7.0.3 or 8.0.
NOTE: Version 8.0 does not fix the vulnerability in wp6sr.dll.
