Problem Description From the Squid Team's SQUID-2002:3 advisory: - Several bugfixes and cleanup of the Gopher client, both to correct some security issues and to make Squid properly render certain Gopher menus. - Security fixes in how Squid parses FTP directory listings into HTML. - FTP data channels are now sanity checked to match the address of the requested FTP server. This to prevent theft or injection of data. See the new ftp_sanitycheck directive if this sanity check is not desired. - The MSNT auth helper has been updated to v2.0.3+fixes for buffer overflow security issues found in this helper. - A security issue in how Squid forwards proxy authentication credentials has been fixed. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to squid-2.5-20020429.i386.rpm OpenLinux 3.1 Server prior to squid-2.5-20020429.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.
