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.
