    Debian Security Advisory DSA 229-1 securitydebian.org
    http://www.debian.org/security/ Martin Schulze

    Package : imp
    Vulnerability : SQL injection
    Problem-Type : remote
    Debian-specific: no
    CVE Id : CAN-2003-0025

    Jouko Pynnonen discovered a probem with IMP, a web based IMAP mail
    program. Using carefully crafted URLs a remote attacker is able to
    inject SQL code into SQL queries without proper user authentication.
    Even though results of SQL queries aren't directly readable from the
    screen, an attacker might. update his mail signature to contain wanted
    query results and then view it on the preferences page of IMP.

    The impact of SQL injection depends heavily on the underlying database
    and its configuration. If PostgreSQL is used, it's possible to
    execute multiple complete SQL queries separated by semicolons. The
    database contains session id's so the attacker might hijack sessions
    of people currently logged in and read their mail. In the worst case,
    if the hordemgr user has the required privilege to use the COPY SQL
    command (found in PostgreSQL at least), a remote user may read or
    write to any file the database user (postgres) can. The attacker may
    then be able to run arbitrary shell commands by writing them to the
    postgres user's ~/.psqlrc; they'd be run when the user starts the psql
    command which under some configurations happens regularly from a cron
    script.

    For the current stable distribution (woody) this problem has been
    fixed in version 2.2.6-5.1.

    For the old stable distribution (potato) this problem has been
    fixed in version 2.2.6-0.potato.5.1.

    For the unstable distribution (sid) these problems have been fixed in
    version 2.2.6-7.

    We recommend that you upgrade your IMP packages.

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

    wget url
            will fetch 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 below:

    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.
