Linux Advisory Watch - December 10, 2004

Author: Preston St. Pierre

This week, advisories were released for hpsockd, viewvcs, nfs-util, cyrus-imapd,
netatalk, gaim, rhpl, ttfonts, mc, udev, gnome-bluetooth, rsh, mysql, libpng,
glib, gtk, postgresql, shadow-utils, perl, mirrorselect, drakxtools, dietlib,
gzip, rp-ppoe, openssl, ImageMagick, samba, and cups. The distributors include
Debian, Fedora, Gentoo, Mandrake, Red Hat, SuSE, Trustix, and Turbo Linux.

Packet Sniffers

One of the most common ways intruders gain access to more systems
on your network is by employing a packet sniffer on a already
compromised host. This "sniffer" just listens on the Ethernet port
for things like passwd and login and su in the packet stream and
then logs the traffic after that. This way, attackers gain passwords
for systems they are not even attempting to break into. Clear-text
passwords are very vulnerable to this attack.

Example: Host A has been compromised. Attacker installs a sniffer.
Sniffer picks up admin logging into Host B from Host C. It gets the
admins personal password as they login to B. Then, the admin does a
su to fix a problem. They now have the root password for Host B.
Later the admin lets someone telnet from his account to Host Z on
another site. Now the attacker has a password/login on Host Z.

In this day and age, the attacker doesn't even need to compromise a
system to do this: they could also bring a laptop or pc into a
building and tap into your net.

Using ssh or other encrypted password methods thwarts this attack.
Things like APOP for POP accounts also prevents this attack. (Normal
POP logins are very vulnerable to this, as is anything that sends
clear-text passwords over the network.)

  Debian: viewcvs information leak fix
  6th, December, 2004

http://www.linuxsecurity.com/content/view/117406

 
  Mandrake: gzip fix
  7th, December, 2004

The Trustix developers found some insecure temporary file creation
problems in the zdiff, znew, and gzeze supplemental scripts in the gzip
package. These flaws could allow local users to overwrite files via a
symlink attack.

http://www.linuxsecurity.com/content/view/117407

 
  Mandrake: ImageMagick fix
  7th, December, 2004

A vulnerability was discovered in ImageMagick where, due to

  Mandrake: lvml fix
  7th, December, 2004

any file on the system. Mandrakelinux does not install pppoe setuid root,
however the packages have been patched to prevent this problem.

http://www.linuxsecurity.com/content/view/117410

 
  Mandrake: nfs-utils fix
  7th, December, 2004

SGI developers discovered a remote DoS (Denial of Service) condition
in the NFS statd server. rpc.statd did not ignore the "SIGPIPE" signal
which would cause it to shutdown if a misconfigured or malicious peer
terminated the TCP connection prematurely.

http://www.linuxsecurity.com/content/view/117411

 
  Mandrake: openssl fix
  7th, December, 2004

The Trustix developers found that the der_chop script, included
in the openssl package, created temporary files insecurely. This could
allow local users to overwrite files using a symlink attack.

    Trusix
  Trustix: multiple package bugfixes
  9th, December, 2004

NFS statd server where it did not ignore the "SIGPIPE" signal. This could
cause the server to shut down if a client terminates prematurely.

http://www.linuxsecurity.com/content/view/117438

 
    Red
Hat

  SuSE: cyrus-imapd remote command execution
  3rd, December, 2004

Stefan Esser reported various bugs within the Cyrus IMAP Server.
These include buffer overflows and out-of-bounds memory access which could
allow remote attackers to execute arbitrary commands as root. The bugs
occur in the pre-authentication phase, therefore an update is strongly
recommended.
