Description kvajk 1999-08-15 21:42:48 UTC
libtermcap's tgetent() function's bounds-checking is
incomplete, which can result in a buffer overflow from
a bogus termcap file.
I haven't yet come across any real-world security problems
resulting from this, but it should be fixed in any event.

I have a patch which I can supply you with.  Thanks!
