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.

Package : xitalk
Vulnerability : missing privilege release
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2004-0151

Steve Kemp from the GNU/Linux audit project discovered a problem
in xitalk, a talk intercept utility for the X Window System. A
local user can exploit this problem and execute arbitrary commands
under the GID utmp. This could be used by an attacker to remove
traces from the utmp file.

For the stable distribution (woody) this problem has been fixed
in version 1.1.11-9.1woody1.

For the unstable distribution (sid) this problem will be fixed
soon.

We recommend that you upgrade your xitalk package.
