| wu-ftp | ----------------------------//
+---------------------------------+
An overflowable buffer exists in earlier versions of wu-ftpd. An attacker
could gain access to the machine by sending malicious commands.

+---------------------------------+
| imp | ----------------------------//
+---------------------------------+
The webmail frontend IMP has a cross site scripting problem, allowing a
remote attacker to send you an E-mail with a malformed URL that when
clicked on will open your mail session to the attacker, allowing him to
read and delete your E-mails.
Caldera:

Caldera Vendor Advisory:

+---------------------------------+
| rpm | ----------------------------//
+---------------------------------+
A malicious user could exploit this vulnerability by sending a carefully
crafted rpm package to the printing system, which will query the package
to extract the information to print and will execute arbitrary code
choosen by the attacker with the privileges of the lp user.
PLEASE SEE VENDOR ADVISORY FOR UPDATE
Conectiva Vendor Advisory:
http://www.linuxsecurity.com/advisories/other_advisory-1712.html
+---------------------------------+
| postfix | ----------------------------//
+---------------------------------+
Wietse Venema reported[1] a vulnerability[2] in Postfix where a remote
attacker could cause a DoS (denial of service) condition on the server.
The SMTP session log could grow to an unreasonable size and possibly
exhaust the server's memory if no other limits were in place.

+---------------------------------+
| sasl | ----------------------------//
+---------------------------------+
There is a format string bug in the Cyrus SASL library, and the library is
used by sendmail. We are not sure whether this vulnerability can be
exploited remotely just by connecting to sendmail, but if it is, the
attacker would gain root access.

+---------------------------------+
| sendmail | ----------------------------//
+---------------------------------+
An input validation error in sendmail has been discovered by Cade Cairns
of SecurityFocus. This problem can be exploited by local users to gain
root access. It is not exploitable by remote attackers without shell
access. New packages based on sendmail.8.11.6 have been prepared for
Slackware 7.1 and 8.0.
