_____________________________________________________________________________
1. Problem Description
A buffer overflow has been found in libtermcap's tgetent() function.
If a setuid root program uses this function, the user could execute
arbitrary code. SuSE Linux 6.0, 6.1 and 6.2 are not affected, since
the only program using libtermcap is bc. This program is not setuid
root.
2. Impact
If you install a third party product, which is setuid root and linked
against libtermcap, a user could use this buffer overflow to gain root
privileges by supplying his own termcap file.
3. Solution
Updated the termcap package from our FTP server.
