TITLE:
IBM Lotus Notes Client for Linux Insecure File Permissions

SECUNIA ADVISORY ID:
SA27860

VERIFY ADVISORY:
http://secunia.com/advisories/27860/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
IBM Lotus Notes 8.x
http://secunia.com/product/16277/

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.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Linux Magazine.
