Debian -- Security Information Martin Schulze January 26, 2001 - ---------------------------------------------------------------------------- Package : exmh Vulnerability : local insecure tempfile creation Debian-specific: no Former versions of the exmh program used /tmp for storing temporary files. No checks were made to ensure that nobody placed a symlink with the same name in /tmp in the meantime and thus was vulnerable to a symlink attack. This could lead to a malicious local user being able to overwrite any file writable by the user executing exmh. Upstream developers have reported and fixed this. The exmh program now use /tmp/login now unless TMPDIR or EXMHTMPDIR is set. We recommend you upgrade your exmh packages immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. You may use an automated update by adding the resources from the footer to the proper configuration.
