Message-ID: <20021112134518.K623@caldera.com> From: security at caldera.com (security@...dera.com) Subject: Security Update: [CSSA-2002-042.0] Linux: libpng progressive image loading vulnerabilities and other buffer overflows To: bugtraq@...urityfocus.com announce@...ts.caldera.com security-alerts@...uxsecurity.com full-disclosure@...ts.netsys.com ______________________________________________________________________________ SCO Security Advisory Subject: Linux: libpng progressive image loading vulnerabilities and other buffer overflows Advisory number: CSSA-2002-042.0 Issue date: 2002 November 12 Cross reference: ______________________________________________________________________________ 1. Problem Description There are two buffer overflow vulnerabilities in the libpng code: one of which can allow attackers to cause a denial of service, and the other that can cause a denial of service with the possibility of executing arbitrary code. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to libpng-1.0.15-5MR.i386.rpm prior to libpng-devel-1.0.15-5MR.i386.rpm prior to libpng-devel-static-1.0.15-5MR.i386.rpm OpenLinux 3.1.1 Workstation prior to libpng-1.0.15-5MR.i386.rpm prior to libpng-devel-1.0.15-5MR.i386.rpm prior to libpng-devel-static-1.0.15-5MR.i386.rpm OpenLinux 3.1 Server prior to libpng-1.0.15-5MR.i386.rpm prior to libpng-devel-1.0.15-5MR.i386.rpm prior to libpng-devel-static-1.0.15-5MR.i386.rpm OpenLinux 3.1 Workstation prior to libpng-1.0.15-5MR.i386.rpm prior to libpng-devel-1.0.15-5MR.i386.rpm prior to libpng-devel-static-1.0.15-5MR.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.
