DESCRIPTION:
A vulnerability has been reported in TWiki, which can be exploited by
malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to the application improperly

to the macro.

- TWiki-4.3.x (TWikiRelease04x03x00 through TWikiRelease04x03x02)
- TWiki-4.2.x (TWikiRelease04x02x00 through TWikiRelease04x02x04)
- TWiki-4.1.x (TWikiRelease04x01x00 through TWikiRelease04x01x02)
- TWiki-4.0.x (TWikiRelease04x00x00 through TWikiRelease04x00x05)
