* Urgency medium due to security fixes and bug fixes which should reach
  Wheezy quickly.
* New upstream bug fix/security release:
  - Prevent access to external files/URLs via XML entity references.
    xml_parse() would attempt to fetch external files or URLs as needed
    to resolve DTD and entity references in an XML value, thus allowing
    unprivileged database users to attempt to fetch data with the
    privileges of the database server. While the external data wouldn't
    get returned directly to the user, portions of it could be exposed
    in error messages if the data didn't parse as valid XML; and in any
    case the mere ability to check existence of a file might be useful
    to an attacker. (CVE-2012-3489)
  - Prevent access to external files/URLs via "contrib/xml2"'s
    xslt_process().
    libxslt offers the ability to read and write both files and URLs
    through stylesheet commands, thus allowing unprivileged database
    users to both read and write data with the privileges of the
    database server. Disable that through proper use of libxslt's
    security options. (CVE-2012-3488)
    Also, remove xslt_process()'s ability to fetch documents and
    stylesheets from external files/URLs. While this was a documented
    "feature", it was long regarded as a bad idea. The fix for
    CVE-2012-3489 broke that capability, and rather than expend effort
    on trying to fix it, we're just going to summarily remove it.
  - Lots of other bug fixes, see HISTORY/changelog.gz.
