Package        : horde and imp
Problem type   : remote exploit
Debian-specific: no

imp as distributed in Debian GNU/Linux 2.2 suffered from insufficient
checking of user supplied data: the IMP webmail interface did not check
the $from variable which contains the sender address for shell
metacharacters. This could be used to run arbitrary commands on the
server running imp.

To fix this horde (the library imp uses) has been modified to sanitize
$from, and imp has been patched to improve checking of user input.

The updated versions are horde 1.2.1-0 and imp 2.2.1-0, and we strongly
recommend you upgrade both packages immediately.
