From: secure@conectiva.com.br To: conectiva-updates@papaleguas.conectiva.com.br, linuxlist@securityportal.com, lwn@lwn.net, bugtraq@securityfocus.com, security-alerts@linuxsecurity.com Subject: [CLA-2001:409] Conectiva Linux Security Announcement - tcltk Date: Thu, 19 Jul 2001 12:11:23 -0300 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- 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.
