SuSE: New acroread packages fix remote code execution

This update fixes several security issues with the Acrobat Reader package. Multiple unspecified vulnerabilities in Adobe Reader and Acrobat before 8.1.2 have unknown impact and attack vectors. The DOC.print function in the Adobe JavaScript API, as used by Adobe Acrobat and Reader before 8.1.2, allows remote attackers to configure silent non-interactive printing, and trigger the printing of an arbitrary number of copies of a document. Integer overflow in Adobe Reader and Acrobat 8.1.1 and earlier allows remote attackers to execute arbitrary code via crafted arguments to the printSepsWithParams, which triggers memory corruption. Fixed packages are available from ftp.suse.com.

______________________________________________________________________________

1) Problem Description and Brief Discussion

  This version update to 8.1.2 fixes numerous bugs, including some
  security problems.

  While Adobe did not publish any details about those problems yet,
  third parties have listed some.

  The official Adobe page is:
      http://www.adobe.com/support/security/advisories/apsa08-01.html

  CVE-2008-0655: Multiple unspecified vulnerabilities in Adobe Reader
                 and Acrobat before 8.1.2 have unknown impact and
                 attack vectors.

  CVE-2008-0667: The DOC.print function in the Adobe JavaScript API,
                 as used by Adobe Acrobat and Reader before 8.1.2, allows
                 remote attackers to configure silent non-interactive
                 printing, and trigger the printing of an arbitrary
                 number of copies of a document.

  CVE-2008-0726: Integer overflow in Adobe Reader and Acrobat 8.1.1 and
                 earlier allows remote attackers to execute arbitrary
                 code via crafted arguments to the printSepsWithParams,
                 which triggers memory corruption.

  Packages for SUSE Linux Enterprise Server 9 and Novell Linux Desktop
  9 are not yet available, since we cannot upgrade to Acrobat Reader 8
  on those machines. As soon as a fixed Acrobat Reader 7 is released,
  they will receive updates.

2) Solution or Work-Around

  A workaround would be to use one of the many Opensource PDF readers,
  like kpdf, evince, xpdf or others.

3) Special Instructions and Notes

  Please close and restart all running instances of Acrobat Reader 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 

   replacing  with the name of the file where you saved the
   announcement. The output for a valid signature looks like:

     gpg: Signature made  using RSA key ID 3D25D3D9
     gpg: Good signature from "SuSE Security Team "

   where  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:

   opensuse-security@opensuse.org
       -   General Linux and SUSE security discussion.
           All SUSE security announcements are sent to this list.
           To subscribe, send an e-mail to
               .

   opensuse-security-announce@opensuse.org
       -   SUSE's announce-only mailing list.
           Only SUSE's security announcements are sent to this list.
           To subscribe, send an e-mail to
