Debian: New calife packages fix buffer overflow

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. Fixed packages are available from security.debian.org.

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.
