        6) Authenticity Verification and Additional Information


1) Problem Description and Brief Discussion

   The Mozilla Firefox browser was updated to fix various bugs and
   security issues.

   On all SUSE Linux Enterprise products it was updated to the stable
   version 3.5.4, on openSUSE 11.0 and 11.1 it was updated to the stable

   Following security issues have been fixed:
   MFSA 2009-52 / CVE-2009-3370:
   Security researcher Paul Stone reported that a user's form history,
   both from web content as well as the smart location bar, was vulnerable
   to theft. A malicious web page could synthesize events such as mouse
   focus and key presses on behalf of the victim and trick the browser
   into auto-filling the form fields with history entries and then
   reading the entries.

   MFSA 2009-53 / CVE-2009-3274:
   Security researcher Jeremy Brown reported that the file naming scheme
   used for downloading a file which already exists in the downloads
   folder is predictable. If an attacker had local access to a victim's
   computer and knew the name of a file the victim intended to open
   through the Download Manager, he could use this vulnerability to
   place a malicious file in the world-writable directory used to save
   temporary downloaded files and cause the browser to choose the
   incorrect file when opening it. Since this attack requires local
   access to the victim's machine, the severity of this vulnerability
   was determined to be low.

   MFSA 2009-54 / CVE-2009-3371:
   Security researcher Orlando Berrera of Sec Theory reported that
   recursive creation of JavaScript web-workers can be used to create a
   set of objects whose memory could be freed prior to their use. These
   conditions often result in a crash which could potentially be used
   by an attacker to run arbitrary code on a victim's computer.

   MFSA 2009-55 / CVE-2009-3372:
   Security researcher Marco C. reported a flaw in the parsing of regular
   expressions used in Proxy Auto-configuration (PAC) files. In certain
   cases this flaw could be used by an attacker to crash a victim's
   browser and run arbitrary code on their computer. Since this
   vulnerability requires the victim to have PAC configured in their
   environment with specific regular expressions which can trigger the
   crash, the severity of the issue was determined to be moderate.

   MFSA 2009-56 / CVE-2009-3373:
   Security research firm iDefense reported that researcher regenrecht
   discovered a heap-based buffer overflow in Mozilla's GIF image
   parser. This vulnerability could potentially be used by an attacker
   to crash a victim's browser and run arbitrary code on their computer.

   MFSA 2009-57 / CVE-2009-3374:
   Mozilla security researcher moz_bug_r_a4 reported that the XPCOM
   utility XPCVariant::VariantDataToJS unwrapped doubly-wrapped objects
   before returning them to chrome callers. This could result in chrome
   privileged code calling methods on an object which had previously been
   created or modified by web content, potentially executing malicious
   JavaScript code with chrome privileges.

   MFSA 2009-59 / CVE-2009-1563:
   Security researcher Alin Rad Pop of Secunia Research reported a
   heap-based buffer overflow in Mozilla's string to floating point
   number conversion routines. Using this vulnerability an attacker
   could craft some malicious JavaScript code containing a very long
   string to be converted to a floating point number which would result
   in improper memory allocation and the execution of an arbitrary memory
   location. This vulnerability could thus be leveraged by the attacker
   to run arbitrary code on a victim's computer.

   MFSA 2009-61 / CVE-2009-3375:
   Security researcher Gregory Fleischer reported that text within a
   selection on a web page can be read by JavaScript in a different domain
   using the document.getSelection function, violating the same-origin
   policy. Since this vulnerability requires user interaction to exploit,
   its severity was determined to be moderate.

   MFSA 2009-62 / CVE-2009-3376:
   Mozilla security researchers Jesse Ruderman and Sid Stamm reported
   that when downloading a file containing a right-to-left override
   character (RTL) in the filename, the name displayed in the dialog
   title bar conflicts with the name of the file shown in the dialog
   body. An attacker could use this vulnerability to obfuscate the name
   and file extension of a file to be downloaded and opened, potentially
   causing a user to run an executable file when they expected to open
   a non-executable file.

   MFSA 2009-63 / CVE-2009-3377 / CVE-2009-3379 / CVE-2009-3378
   Mozilla upgraded several third party libraries used in media rendering
   to address multiple memory safety and stability bugs identified by
   members of the Mozilla community. Some of the bugs discovered could
   potentially be used by an attacker to crash a victim's browser and
   execute arbitrary code on their computer. liboggz, libvorbis, and
   liboggplay were all upgraded to address these issues.  Audio and
   video capabilities were added in Firefox 3.5 so prior releases
   of Firefox were not affected.  Georgi Guninski reported a crash in
   liboggz. (CVE-2009-3377), Lucas Adamski, Matthew Gregan, David Keeler,
   and Dan Kaminsky reported crashes in libvorbis. (CVE-2009-3379),
   Juan Becerra reported a crash in liboggplay (CVE-2009-3378).

   MFSA 2009-64 / CVE-2009-3380 / CVE-2009-3381 / CVE-2009-3382 / CVE-2009-3383:
   Mozilla developers and community members identified and fixed
   several stability bugs in the browser engine used in Firefox and other
   Mozilla-based products. Some of these crashes showed 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.

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 and xulrunner using programs 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 <file.rpm>

   to apply the update, replacing <file.rpm> 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

      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

    The internal 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, replacing <file.rpm> with the
    filename of the RPM package downloaded. The package is unmodified if it
    contains a valid signature from 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.

  - SUSE runs two security mailing lists to which any interested party may
