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.
