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.
