    1. Topic:

    An updated gaim package that fixes several security issues is now
    available.

    2. Relevant releases/architectures:

    Red Hat Linux 7.3 - i386
    Red Hat Linux 9 - i386

    3. Problem description:

    Issues fixed with this gaim release include:

    Multiple buffer overflows that affect versions of Gaim 0.75 and earlier.
    1) When parsing cookies in a Yahoo web connection, 2) YMSG protocol
    overflows parsing the Yahoo login webpage, 3) a YMSG packet overflow, 4)
    flaws in the URL parser, and 5) flaws in HTTP Proxy connect. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0006 to these issues.

    A buffer overflow in Gaim 0.74 and earlier in the Extract Info Field
    Function used for MSN and YMSG protocol handlers. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0007 to this issue.

    An integer overflow in Gaim 0.74 and earlier, when allocating memory for
    a directIM packet results in heap overflow. The Common Vulnerabilities
    and Exposures project (cve.mitre.org) has assigned the name
    CAN-2004-0008 to this issue.

    Buffer overflow bugs were found in the Gaim MSN protocol handler. In
    order to exploit these bugs, an attacker would have to perform a man in
    the middle attack between the MSN server and the vulnerable Gaim client.
    Such an attack could allow arbitrary code execution. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0500 to this issue.

    An integer overflow bug has been found in the Gaim Groupware message
    receiver. It is possible that if a user connects to a malicious server,
    an attacker could send carefully crafted data which could lead to
    arbitrary code execution on the victims machine. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0754 to this issue.

    A shell escape bug has been found in the Gaim smiley theme file
    installation. When a user installs a smiley theme, which is contained
    within a tar file, the unarchiving of the data is done in an unsafe
    manner. An attacker could create a malicious smiley theme that would
    execute arbitrary commands if the theme was installed by the victim. The
    Common Vulnerabilities and Exposures project (cve.mitre.org) has
    assigned the name CAN-2004-0784 to this issue.

    Buffer overflow bugs have been found in the Gaim URL decoder, local
    hostname resolver, and the RTF message parser. It is possible that a
    remote attacker could send carefully crafted data to a vulnerable client
    and lead to a crash or arbitrary code execution. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0785 to this issue.

    Users of Gaim are advised to upgrade to this updated package which
    contains Gaim version 0.82.1 and is not vulnerable to these issues.

    4. Solution:

    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.

    To update all RPMs for your particular architecture, run:

    rpm -Fvh [filenames]

    where [filenames] is a list of the RPMs you wish to upgrade. Only those
    RPMs which are currently installed will be updated. Those RPMs which
    are not installed but included in the list will not be updated. Note
    that you can also use wildcards (*.rpm) if your current directory *only*
    contains the desired RPMs.

    Please note that this update is also available via yum and apt. Many
    people find this an easier way to apply updates. To use yum issue:

    yum update

    or to use apt:

    apt-get update; apt-get upgrade

    This will start an interactive process that will result in the
    appropriate RPMs being upgraded on your system. This assumes that you
    have yum or apt-get configured for obtaining Fedora Legacy content.
    Please visit http://www fedoralegacy.org/docs for directions on how to
    configure yum and apt-get.

    These packages are GPG signed by Fedora Legacy for security. Our key is
    available from http://www.fedoralegacy org/about/security.php

    You can verify each package with the following command:

        rpm --checksig -v <filename>

    If you only wish to verify that each package has not been corrupted or
    tampered with, examine only the sha1sum with the following command:

        sha1sum <filename>
