DESCRIPTION:
Tim Brown has discovered a vulnerability in Psi, which can be
exploited by malicious people to conduct spoofing attacks.

The vulnerability is caused due to Psi not properly setting the text
format when displaying certificate information, which can be
exploited to spoof certificates via e.g. certificates containing
specially crafted RTF data in the Common Name (CN) field.

The vulnerability is confirmed in version 0.14.0. Other versions may
also be affected.

SOLUTION:
Do not rely on the displayed certificate information.

PROVIDED AND/OR DISCOVERED BY:
Tim Brown, Nth Dimension.
