-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SCO Security Advisory Subject: OpenLinux: mc Updated packages resolve local buffer overflow vulnerability Advisory number: CSSA-2004-014.0 Issue date: 2004 March 25 Cross reference: sr889551 fz528937 erg712553 CAN-2003-1023 ______________________________________________________________________________ 1. Problem Description Stack-based buffer overflow in vfs_s_resolve_symlink of vfs/direntry.c for Midnight Commander (mc) 4.6.0 and earlier, and possibly later versions, allows remote attackers to execute arbitrary code during symlink conversion. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-1023 to this issue. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to mc-4.5.51-6.i386.rpm prior to mc-doc-4.5.51-6.i386.rpm OpenLinux 3.1.1 Workstation prior to mc-4.5.51-6.i386.rpm prior to mc-doc-4.5.51-6.i386.rpm 3. Solution The proper solution is to install the latest packages. Unix users with Linux Kernel Personality can 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.
