Problem Description gv can be forced to execute arbitrary shell commands by using a buffer overflow. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to gv-3.5.8-10.i386.rpm prior to gv-doc-html-3.5.8-10.i386.rpm OpenLinux 3.1.1 Workstation prior to gv-3.5.8-10.i386.rpm prior to gv-doc-html-3.5.8-10.i386.rpm OpenLinux 3.1 Server prior to gv-3.5.8-10.i386.rpm prior to gv-doc-html-3.5.8-10.i386.rpm OpenLinux 3.1 Workstation prior to gv-3.5.8-10.i386.rpm prior to gv-doc-html-3.5.8-10.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.
