Package        : calife
Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2004-0188
Debian bug     : 235157

Calife, a program which provides super user privileges to specific
users, was found to contain a buffer overflow related to the
getpass(3) library function.  A local attacker could potentially
exploit this vulnerability, given knowledge of a local user's password
and the presence of at least one entry in /etc/calife.auth, to execute
arbitrary code with root privileges.

For the current stable distribution (woody) this problem has been
fixed in version 2.8.4c-1woody1.

For the unstable distribution (sid) this problem has been fixed in
version 2.8.6-1.

We recommend that you update your calife package.

Upgrade Instructions

dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
