Debian Security Advisory DSA-022-1 security@debian.org
http://www.debian.org/security/ Martin Schulze

----------------------------------------------------------------------------

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.
