Description:
Some security issues have been reported in Lotus Notes for Linux, which can be exploited by malicious, local users to gain escalated privileges.
1) Files extracted from the installation kit archive are given world-writable permissions. This can be exploited to modify the installation kit and place malicious content, which is then later executed when the installer is run.
2) An error exists in setup.sh contained within the installation kit when setting permissions for the "installdata" binary. This can be exploited to replace the "installdata" file with a malicious binary, which is then later executed when setup.sh is run.
The security issues are reported in version 8.0. Other versions may also be affected.
Solution:
Restrict access to trusted users only (see the vendor's advisory for details).
The vendor will reportedly fix the security issues with the release of version 8.0.1.
