From: security at caldera.com (security@...dera.com) Subject: Security Update: [CSSA-2002-045.0] Linux: python insecure temporary files in os._execvpe To: bugtraq@...urityfocus.com announce@...ts.caldera.com security-alerts@...uxsecurity.com full-disclosure@...ts.netsys.com ______________________________________________________________________________ SCO Security Advisory Subject: Linux: python insecure temporary files in os._execvpe Advisory number: CSSA-2002-045.0 Issue date: 2002 November 14 Cross reference: ______________________________________________________________________________ 1. Problem Description os._execvpe from os.py in Python creates temporary files with predictable names, which could allow local users to execute arbitrary code via a symlink attack. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to python-1.5.2-23.i386.rpm prior to python-devel-1.5.2-23.i386.rpm prior to python-docs-1.5.2-23.i386.rpm prior to python-tools-1.5.2-23.i386.rpm OpenLinux 3.1.1 Workstation prior to python-1.5.2-23.i386.rpm prior to python-devel-1.5.2-23.i386.rpm prior to python-docs-1.5.2-23.i386.rpm prior to python-tools-1.5.2-23.i386.rpm OpenLinux 3.1 Server prior to python-1.5.2-23.i386.rpm prior to python-devel-1.5.2-23.i386.rpm prior to python-docs-1.5.2-23.i386.rpm prior to python-tools-1.5.2-23.i386.rpm OpenLinux 3.1 Workstation prior to python-1.5.2-23.i386.rpm prior to python-devel-1.5.2-23.i386.rpm prior to python-docs-1.5.2-23.i386.rpm prior to python-tools-1.5.2-23.i386.rpm 3. Solution The proper solution is to install the latest packages. Many customers find it easier to use the Caldera System Updater, called cupdate (or kcupdate under the KDE environment), to update these packages rather than downloading and installing them by hand. 4.
