1) problem description, brief discussion

This security update for Mozilla Firefox fixes following problems:

- CAN-2005-0231: "Fire tabbing"
The javascript security manager usually prevents that a javascript:
URL from one host is opened in a window displaying content from
another host. But when the link is dropped to a tab, the security
manager does not kick in.

This can lead to several security problems scaling from stealing
session cookies to the ability to run arbitrary code on the client
system (depending on the displayed site or security settings).

- CAN-2005-0232: "Fire flashing"

Using plugins like Flash and the -moz-opacity filter it is possible
to display the about:config site in a hidden frame or a new window.

By making the user double-click at a specific screen position
(e.g. using a DHTML game) you can silently toggle the status of
boolean config parameters.

- CAN-2005-0233: "homograph attacks" / "IDN cloaking"

Attackers may spoof host names by using translated host name
representation which look exactly the same as the original host,
allowing phishing attacks or similar.

We now show both IDN punycode and visible form of the host name.

- CAN-2005-0255:

Attackers could cause overflows or crashes in low memory situations.

- Added additional Firefox bugfixes from the 1.0.1 release.


Only the listed distributions are affected, others do not ship
Mozilla Firefox.

Also note that Firefox was called Firebird in SUSE Linux 9.0.

2) solution/workaround

Please install the updated packages. There is no workaround (except
using a different browser).

3) special instructions and notes

Make sure you restart the browser after installing the update.

4) package location and checksums

Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

6) standard appendix: authenticity verification, additional information

- Package authenticity verification:

SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.

1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SUSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key security@suse.de),
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.

2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SUSE Linux distributions version 7.1 and thereafter install the
key "build@suse.de" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
