    Synopsis: Updated glibc packages provide security and bug fixes
    Advisory ID: RHSA-2003:325-01
    Issue date: 2003-11-12
    Updated on: 2003-11-12
    Product: Red Hat Linux
    Keywords: netlink getgrouplist
    Cross references:
    Obsoletes: RHSA-2003:212
    CVE Names: CAN-2003-0689 CAN-2003-0859
    - ---------------------------------------------------------------------

    1. Topic:

    Updated glibc packages that resolve vulnerabilities and address several bugs
    are now available.

    2. Relevant releases/architectures:

    Red Hat Linux 7.1 - i386, i686
    Red Hat Linux 7.2 - i386, i686, ia64
    Red Hat Linux 7.3 - i386, i686
    Red Hat Linux 8.0 - i386, i686
    Red Hat Linux 9 - i386, i686

    3. Problem description:

    The glibc packages contain GNU libc, which provides standard system libraries.

    A bug in the getgrouplist function can cause a buffer overflow if
    the size of the group list is too small to hold all the user's groups.
    This overflow can cause segmentation faults in user applications, which may
    have security implications, depending on the application in question. This
    vulnerability exists only when an administrator has placed a user in a
    number of groups larger than that expected by an application. Therefore,
    there is no risk in instances where users are members of few groups. The
    Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
    the name CAN-2003-0689 to this issue.

    Herbert Xu reported that various applications can accept spoofed messages
    sent on the kernel netlink interface by other users on the local machine.
    This could lead to a local denial of service attack. In Red Hat Linux 9
    and later, the glibc function getifaddrs uses netlink and could therefore
    be vulnerable to this issue. The Common Vulnerabilities and Exposures
    project (cve.mitre.org) has assigned the name CAN-2003-0859 to this issue.

    In addition to the security issues, a number of other bugs were fixed.

    Users are advised to upgrade to these erratum packages, which contain a
    patch that checks that netlink messages actually came from the kernel, a
    backported security patch for the getgroups list vulnerability, and patches
    for the various bug fixes.

    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 the following
    command at a shell prompt:

    rpm -Fvh [filenames]

    where [filenames] is a list of the RPMs you wish to upgrade. On the i686
    architecture, *.i686.rpm packages should be installed where available
    rather than *.i386.rpm.

    If you are unsure which architecture you are on, run the following
    command at a shell prompt:

    rpm -q --qf '%{arch}\n' glibc

    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 Red Hat Network. Many
    people find this an easier way to apply updates. To use Red Hat Network,
    launch the Red Hat Update Agent with the following command:

    up2date

    This will start an interactive process that will result in the appropriate
    RPMs being upgraded on your system.

    If up2date fails to connect to Red Hat Network due to SSL Certificate
    Errors, you need to install a version of the up2date client with an updated
    certificate. The latest version of up2date is available from the Red Hat
    FTP site and may also be downloaded directly from the RHN website:

    https://rhn.redhat.com/help/latest-up2date.pxt
