Caldera International, Inc. Security Advisory
Subject: Linux: multiple vulnerabilities in openssl
Advisory number: CSSA-2002-033.0
Issue date: 2002 July 31

1. Problem Description
There are four remotely exploitable buffer overflows that affect
various OpenSSL client and server implementations. There are also
encoding problems in the ASN.1 library used by OpenSSL. Several
of these vulnerabilities could be used by a remote attacker to
execute arbitrary code on the target system. All could be used
to create denial of service.
2. Vulnerable Supported Versions
System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to openssl-0.9.6-18.i386.rpm
prior to openssl-devel-0.9.6-18.i386.rpm
prior to openssl-devel-static-0.9.6-18.i386.rpm
OpenLinux 3.1.1 Workstation prior to openssl-0.9.6-18.i386.rpm
prior to openssl-devel-0.9.6-18.i386.rpm
prior to openssl-devel-static-0.9.6-18.i386.rpm
OpenLinux 3.1 Server prior to openssl-0.9.6-18.i386.rpm
prior to openssl-devel-0.9.6-18.i386.rpm
prior to openssl-devel-static-0.9.6-18.i386.rpm
OpenLinux 3.1 Workstation prior to openssl-0.9.6-18.i386.rpm
prior to openssl-devel-0.9.6-18.i386.rpm
prior to openssl-devel-static-0.9.6-18.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.
