______________________________________________________________________________
1) Problem Description and Brief Discussion
The Mozilla Firefox packages were brought to security update version
2.0.0.10 for SUSE Linux Enterprise 10, SUSE Linux 10.0, 10.1 and
openSUSE 10.2 and 10.3.
These packages include the Canvas regression fix also fixed in
2.0.0.11, so we are effectively at 2.0.0.11 with our packages.
Mozilla Firefox for Novell Linux Desktop 9 is still being prepared,
same for Mozilla Thunderbird 2.0.0.9 and Mozilla and Seamonkey Suite
packages.
The update was released on 29th of November.
Following security problems were fixed:
MFSA 2007-37 / CVE-2007-5947: The jar protocol handler in Mozilla
Firefox retrieves the inner URL regardless of its MIME type, and
considers HTML documents within a jar archive to have the same origin
as the inner URL, which allows remote attackers to conduct cross-site
scripting (XSS) attacks via a jar: URI.
MFSA 2007-38 / CVE-2007-5959:
The Firefox 2.0.0.10 update contains fixes for three bugs that improve
the stability of the product. These crashes showed some evidence of
memory corruption under certain circumstances and we presume that
with enough effort at least some of these could be exploited to run
arbitrary code.
MFSA 2007-39 / CVE-2007-5960:
Gregory Fleischer demonstrated that it was possible to generate a fake
HTTP Referer header by exploiting a timing condition when setting the
window.location property. This could be used to conduct a Cross-site
Request Forgery (CSRF) attack against websites that rely only on the
Referer header as protection against such attacks.
2) Solution or Work-Around
There is no known workaround, please install the update packages.
3) Special Instructions and Notes
Please close and restart all running instances of Firefox after the update.
4) Package Location and Checksums
The preferred method for installing security updates is to use the YaST
Online Update (YOU) tool. YOU detects which updates are required and
automatically performs the necessary steps to verify and install them.
Alternatively, download the update packages for your distribution manually
and verify their integrity by the methods listed in Section 6 of this
announcement. Then install the packages using the command
rpm -Fhv
to apply the update, replacing with the filename of the
downloaded RPM package.

6) Authenticity Verification and Additional Information
- Announcement authenticity verification:
SUSE security announcements are published via mailing lists and on Web
sites. The authenticity and integrity of a SUSE security announcement is
guaranteed by a cryptographic signature in each announcement. All SUSE
security announcements are published with a valid signature.
To verify the signature of the announcement, save it as text into a file
and run the command
gpg --verify <file>
replacing <file> with the name of the file where you saved the
announcement. The output for a valid signature looks like:
gpg: Signature made <DATE> using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team "
where <DATE> is replaced by the date the document was signed.
If the security team's key is not contained in your key ring, you can
import it from the first installation CD. To import the key, use the
command
gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc
- Package authenticity verification:
SUSE update packages are available on many mirror FTP servers all over the
world. While this service is considered valuable and important to the free
and open source software community, the authenticity and the integrity of
a package needs to be verified to ensure that it has not been tampered
with.
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) Using the internal gpg signatures of the rpm package
2) MD5 checksums as provided in this announcement
1) The internal rpm package signatures provide an easy way to verify the
authenticity of an RPM package. Use the command
rpm -v --checksig
to verify the signature of the package, replacing with the
filename of the RPM package downloaded. The package is unmodified if it
contains a valid signature from build@suse.de with the key ID 9C800ACA.
This key is automatically imported into the RPM database (on
RPMv4-based distributions) and the gpg key ring of 'root' during
installation. You can also find it on the first installation CD and at
the end of this announcement.
2) If you need an alternative means of verification, use the md5sum
command to verify the authenticity of the packages. Execute the command
md5sum
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
SUSE security announcement. Because the announcement containing the
checksums is cryptographically signed (by security@suse.de), the
checksums show proof of the authenticity of the package if the
signature of the announcement is valid. Note that the md5 sums
published in the SUSE Security Announcements are valid for the
respective packages only. Newer versions of these packages cannot be
verified.
- SUSE runs two security mailing lists to which any interested party may
subscribe:
