"Several buffer overflows were fixed in the 'ncurses' library in
November 2000. Unfortunately, one was missed. This can lead to crashes
when using ncurses applications in large windows.

The Common Vulnerabilities and Exposures project has assigned the name
CAN-2002-0062 to this issue.

This problem has been fixed for the stable release of Debian in
version 5.0-6.0potato2. The testing and unstable releases contain
ncurses 5.2, which is not affected by this problem.

There are no known exploits for this problem, but we recommend that
all users upgrade ncurses immediately."
