CONECTIVA LINUX SECURITY ANNOUNCEMENT 
-------------------------------------------------------------------------

PACKAGE   : bash
SUMMARY   : Insecure temporary file creation in << redirects
DATE      : 2000-12-05 18:14:00
ID        : CLA-2000:350
RELEVANT
RELEASES  : 4.0, 4.0es, 4.1, 4.2, 5.0, prg gráficos, ecommerce, 5.1, 6.0

------------------------------------------------------------------------

DESCRIPTION
 Bash is the default shell used in a standard Conectiva Linux
 installation.
 There is a vulnerability regarding the use of "<<" redirectors. If
 used, the shell creates a temporary file in /tmp with a predictable
 filename (the only variant is the PID). Additionally, it was not
 being opened exclusively. This can be used by an attacker to
 overwrite arbitrary files in the system. At least one initialization
 script (rc.sysinit) uses "<<", and it is run as root at boot time.


SOLUTION
 All users should upgrade immediately.
