Description:
Secunia Research has discovered a security issue in IBM Lotus Notes, which can be exploited by malicious, local users to manipulate arbitrary files.

The problem is that Lotus Notes sets insecure default permissions (grants "Everyone" group "Full Control") on the "notes" directory and all child objects. This can be exploited to remove, manipulate, and replace any of the application's files.

The security issue is confirmed in versions 6.5.4, 6.5.5, 7.0.0, and 7.0.1.

Solution:
Update to version 7.0.2.

The security issue will reportedly also be addressed in version 6.5.6.

Provided and/or discovered by:
Carsten Eiram, Secunia Research.

Changelog:
2006-10-20: Added link to US-CERT.
