8wire.com Review: EnGarde Secure Linux 1.0.1 - EnGarde Secure Linux is a
Linux distribution that allows anyone - including those with no Linux
experience - to easily set up their own secure Web and email servers. We
tested this software on a bare-bones PC and found it very simple to set up
and use. It's a great value for those looking for a fully functional
Internet server that can run on old or inexpensive hardware.

+---------------------------------+
| mailman | ----------------------------//
+---------------------------------+
Barry A. Warsaw reported several cross-site scripting security holes in
Mailman, due to on-existent escaping of CGI variables. These have been
fixed upstream in version 2.0.8, and the relevant patches have been
backported to version 1.1-10 in Debian.
Debian Intel IA-32 architecture:

binary-i386/mailman_1.1-10_i386.deb
MD5 checksum: 27c9d400360a99b39954f563f5d0ed43
Debian Vendor Advisory:
http://www.linuxsecurity.com/advisories/debian_advisory-1751.html
+---------------------------------+
| htdig | ----------------------------//
+---------------------------------+
A remote attacker may use htsearch as a kind of denial-of-service attack
by causing it to read a never-ending special file such as `/dev/null'.
FreeBSD [i386]
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/
textproc/htdig-3.1.5_1.tgz
FreeBSD Vendor Advisory:
http://www.linuxsecurity.com/advisories/freebsd_advisory-1753.html
+---------------------------------+
| xsane | ----------------------------//
+---------------------------------+
A local user may be able to cause xsane (run by another user) to overwrite
any file for which the latter user has sufficient privilege. While it is
advisable to run XSane with a non-privileged user account, many users run
it using the root account, increasing the risk.
FreeBSD [i386]
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/
graphics/xsane-0.82.tgz
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/
graphics/xsane-0.82.tgz
FreeBSD Vendor Advisory:
http://www.linuxsecurity.com/advisories/freebsd_advisory-1754.html
+---------------------------------+
| OpenSSH | ----------------------------//
+---------------------------------+
A malicious local user can pass environment variables to the login process
if the administrator enables the UseLogin option. This can be abused to
bypass authentication and gain root access. Note that this option is not
enabled by default on TSL.
Mandrake:

+---------------------------------+
| kerberos | ----------------------------//
+---------------------------------+
A buffer overflow exists in the telnet portion of Kerberos that could
provide root access to local users. MDKSA-2001:068 provided a similar fix
to the normal telnet packages, but the Kerberized equivalent was not
updated previously.
Mandrake:
PLEASE SEE VENDOR ADVISORY
Mandrake Vendor Advisory:
http://www.linuxsecurity.com/advisories/mandrake_advisory-1755.html
+---------------------------------+
| libgtop | ----------------------------//
+---------------------------------+
A remote format string vulnerability was found in the libgtop daemon by
Laboratory intexxia. By sending a specially crafted format string to the
server, a remote attacker could potentially execute arbitrary code on the
remote system with the daemon's permissions.

+---------------------------------+
| glibc | ----------------------------//
+---------------------------------+
While researching the recent globbing bugs in wu-ftpd, Flavio Veloso
discovered (with the assistance of Jakub Jelinek ) a buffer overflow in
glibc's glob(3) implementation. This vulnerability can only be triggered
by programs that use glibc's globbing functions.
