SCO Security Advisory
Subject: Linux: several recently discovered openssl vulnerabilities
Advisory number: CSSA-2003-014.0
Issue date: 2003 March 21
Cross reference:
______________________________________________________________________________
1. Problem Description
Dan Boneh and David Brumley have successfully implemented an
RSA timing attack against openssl. This updated version guards
against this attack. In an upcoming paper, Brice Canvel (EPFL),
Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and Martin Vuagnoux
(EPFL, Ilion) describe and demonstrate a timing-based attack on
CBC ciphersuites in SSL and TLS.
2. Vulnerable Supported Versions
System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to openssl-0.9.6-21.i386.rpm
prior to openssl-devel-0.9.6-21.i386.rpm
prior to openssl-devel-static-0.9.6-21.i386.rpm
OpenLinux 3.1.1 Workstation prior to openssl-0.9.6-21.i386.rpm
prior to openssl-devel-0.9.6-21.i386.rpm
prior to openssl-devel-static-0.9.6-21.i386.rpm
OpenLinux 3.1 Server prior to openssl-0.9.6-21.i386.rpm
prior to openssl-devel-0.9.6-21.i386.rpm
prior to openssl-devel-static-0.9.6-21.i386.rpm
OpenLinux 3.1 Workstation prior to openssl-0.9.6-21.i386.rpm
prior to openssl-devel-0.9.6-21.i386.rpm
prior to openssl-devel-static-0.9.6-21.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.
