    - -------------------------------------------------------------------------- Debian Security Advisory DSA 2054-2 [email protected] http://www.debian.org/security/ Martin Schulze

    - --------------------------------------------------------------------------

    Package : bind9
    Vulnerability : DNS cache poisoning
    Problem type : remote
    Debian-specific: no
    CVE Id(s) : CVE-2010-0097 CVE-2010-0290 CVE-2010-0382

    This update restores the PID file location for bind to the location
    before the last security update. For reference, here is the original
    advisory text that explains the security problems fixed:

    Several cache-poisoning vulnerabilities have been discovered in BIND.
    These vulnerabilities are apply only if DNSSEC validation is enabled and
    trust anchors have been installed, which is not the default.

    The Common Vulnerabilities and Exposures project identifies the
    following problems:

    CVE-2010-0097
    BIND does not properly validate DNSSEC NSEC records, which allows
    remote attackers to add the Authenticated Data (AD) flag to a forged
    NXDOMAIN response for an existing domain.

    CVE-2010-0290
    When processing crafted responses containing CNAME or DNAME records,
    BIND is subject to a DNS cache poisoning vulnerability, provided that
    DNSSEC validation is enabled and trust anchors have been installed.

    CVE-2010-0382
    When processing certain responses containing out-of-bailiwick data,
    BIND is subject to a DNS cache poisoning vulnerability, provided that
    DNSSEC validation is enabled and trust anchors have been installed.

    In addition, this update introduce a more conservative query behavior
    in the presence of repeated DNSSEC validation failures, addressing the
    "roll over and die" phenomenon. The new version also supports the
    cryptographic algorithm used by the upcoming signed ICANN DNS root
    (RSASHA256 from RFC 5702), and the NSEC3 secure denial of existence
    algorithm used by some signed top-level domains.

    This update is based on a new upstream version of BIND 9, 9.6-ESV-R1.
    Because of the scope of changes, extra care is recommended when
    installing the update. Due to ABI changes, new Debian packages are
    included, and the update has to be installed using "apt-get
    dist-upgrade" (or an equivalent aptitude command).

    For the stable distribution (lenny), these problems have been fixed in
    version 1:9.6.ESV.R1+dfsg-0+lenny2.

    The unstable distribution is not affected by the wrong PID file location.

    We recommend that you upgrade your bind9 packages.


    Upgrade Instructions
    - --------------------

    wget url
    will flenny the file for you
    dpkg -i file.deb
    will install the referenced file.

    If you are using the apt-get package manager, use the line for
    sources.list as given at the end of this advisory:

    apt-get update
    will update the internal database
    apt-get upgrade
    will install corrected packages

    You may use an automated update by adding the resources from the
    footer to the proper configuration.
