4) Description of Vulnerability
Secunia Research has discovered a vulnerability in Lotus Notes, which
potentially can be exploited by malicious people to compromise a
user's system.
The vulnerability is caused due to a boundary error in the TAR reader
(tarrdr.dll) when extracting files from a TAR archive. This can be
exploited to cause a stack-based buffer overflow via a TAR archive
containing a file with a long filename.
Successful exploitation allows execution of arbitrary code, but
requires that the user views a malicious TAR archive and chooses to
extracts a compressed file to a directory with a very long path
(more than 220 bytes).

5) Solution
Update to version 6.5.5 or 7.0.1.
