This bug was fixed in the package snort - 2.9.2-3ubuntu1

---------------
snort (2.9.2-3ubuntu1) precise; urgency=low

  * Merge from Debian testing. (LP: #931454)  Remaining changes:
    - debian/rules: use mysql_config to find libraries to fix FTBFS with
      multiarch libmysqlclient.
  * Dropped "Fixed typo in snort.8": patched upstream.

snort (2.9.2-3) unstable; urgency=low

  * Restore code from the 2.8.5.2-5 package onwards which was lost when
    the version of experimental was moved to the archive.
     - Now /var/lib/snort is created through package configuration, as
       it should have been
     - Remove md5sum files when purging (Closes: #657038)
  * debian/rules:
      - Enable IPv6 support which was optional in version 2.8 for the Snort
        binary package. This is not enabled for the database binary packages
        (snort-pgsql and snort-mysql) as the database schemas do not support
        IPv6.  (Closes: #633064) (LP: #703707)
      - Include the quilt makefile and add dependencies in -stamp and
        clean targets
  * debian/snort.init.d:
      - Do not abort if the package is not configured to use a database but
        the db-pending-config semaphore is found.  Remove it instead and
        continue. This can happen if a database-related package was installed,
        removed and then 'snort' is installed afterwards.
        (LP: #316878, #639755, #722488, #754230, #798608, #876615, #816634, #891904, #918250)
  * debian/snort-{mysql,pgsql}.postrm:
      - Remove the db-pending-config semaphore file when removing the package.
        This prevents errors with the snort.init.d logic if a database package
        is left unconfigured and then replaced with the snort (non-database)
        package.
  * debian/README-database.Debian: Indicate that database support will be
    deprecated in 2.9 and document that IPv6 is not supported either
  * debian/control:
     - Add Build-Depends on quilt
     - Add VCS entries
     - Put the complete maintainer's name in UTF-8
     - Change Uploaders, add Andrew Pollock and remove Pascal Hakim
     - Update Standards Version

snort (2.9.2-2) unstable; urgency=low

  * debian/control:  Add net-tools to Depends: of snort, snort-mysql and
    snort-pgsql since 'ifconfig' is required for the configuration script
    to work. (Closes: #656445)
  * debian/snort{,-mysql,-psql}.postinst: Create the checksum directory if it
    does not exist right at the beginning since it might not be created.
    (Closes: #656445)

snort (2.9.2-1) unstable; urgency=low

  [ Andrew Pollock ]
  * New upstream release, upload to unstable
     - Fixes CVE-2009-3641: DoS while printing specially-crafted IPv6 packet
       using the -v option (Closes: 553584)
     - The package no longer build-depends on iptables-dev and the negated list
       of architectures is no longer used (Closes: 634660)
     - debian/patches/config: Patch the configuration file to remove include
       files not currently available (Closes: #619446)
     - This version is fully supported rule-wise (LP: #872582)
  * Switch to dpkg-source 3.0 (quilt) format
  * Port across all changes from Snort 2.8.5.2-5 and later in unstable
  * debian/snort.postinst: create the directory that the checksum for
    snort.debian.conf will be created in if it doesn't already exist
  * debian/rules: tell dh_makeshlibs to not call ldconfig in the
    preinst/postinst of snort-common-libraries
  * debian/rules: don't install README.WIN32 into snort-doc

  [ Javier Fernandez-Sanguino Peña ]
  * debian/rules:
     - Set enable-zlib when configuring all packages to force it to be
       enabled as this is required by the http_inspect preprocessor which
       is enabled by default (Closes: #631854)
     - Included (commented) the patch provided by Clint Byrum and included in
       Ubuntu to prevent snort from FTFS with libmysqlclient-dev which will be
       multiarch in the future. The patch uses mysql_config to find libraries
       to fix FTBFS with multiarch libmysqlclient. Not enabled since the
       version of libmysqlclient in unstable currently does not support the
       --variable=pkglibdir option
  * debian/snort{,-inline}.config: Use LC_ALL=C when calling ifconfig to make
    the postinst work when ifconfig's output is internationalised (Closes: 577033)
  * debian/control: Fix link in the rules package, point to
    http://www.snort.org/snort-rules/ (Closes: 646547)
  * debian/my/snort-stat: Modify so that alerts with Priority but without classification
    are analysed when parsing syslog information. Also set the class to 'Undefined'
    instead of leaving it empty. (Closes: 590061)
  * po-debconf translation updates:
    - Danish, provided by Joe Dalton (Closes: 638678)
    - Dutch, provided by Jeroen Schot (Closes: 654239)
