Message-ID: <20020731111615.R29736@caldera.com> From: security at caldera.com (security@...dera.com) Subject: Security Update: [CSSA-2002-033.0] Linux: multiple vulnerabilities in openssl To: bugtraq@...urityfocus.com announce@...ts.caldera.com security-alerts@...uxsecurity.com full-disclosure@...ts.netsys.com ______________________________________________________________________________ Caldera International, Inc. Security Advisory Subject: Linux: multiple vulnerabilities in openssl Advisory number: CSSA-2002-033.0 Issue date: 2002 July 31 Cross reference: ______________________________________________________________________________ 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. 4.
