From: <secure@conectiva.com.br>

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

PACKAGE   : tcltk
SUMMARY   : Insecure runtime library search path
DATE      : 2001-07-19 12:10:00
ID        : CLA-2001:409
RELEVANT
RELEASES  : 6.0, 7.0

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

DESCRIPTION
 zen-parse reported [1][2] that the "tcl" and "expect" programs were
 looking for dynamic libraries in unsafe directories.
 "expect" searches for dynamic libraries under the world writable
 /var/tmp directory. An attacker could place fake libraries in that
 directory and thus have expect (and progams using it, as mkpasswd)
 execute arbitrary code. A similar problem exists with "tcl". This
 program searches for dynamic libraries in directories under the
 current directory, which is also an unsafe behaviour.
 Conectiva Linux 6.0 is vulnerable to both problems, while the 7.0
 version is only affected by the last one.


SOLUTION
 It is recommended that all users of these programs update their
 packages. For completeness, all packages created from the "tcltk"
 source package are being provided.
