Problem Description mgetty will overflow an internal buffer if the caller name reported by the modem is too long. The faxspool spooling directory used for outgoing faxes was world-writable. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to mgetty-1.1.22_Aug17-13.i386.rpm OpenLinux 3.1.1 Workstation prior to mgetty-1.1.22_Aug17-13.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.
