- 公告与补丁

        One of the following (exerpted from the FreeBSD advisory):
        1) Upgrade your entire ports collection and rebuild the eject port.
        2) Deinstall the old package and install a new package dated after the
        correction date, obtained from:
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/sysutils/eject-1.4.tgz
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/sysutils/eject-1.4.tgz
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/sysutils/eject-1.4.tgz
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/sysutils/eject-1.4.tgz
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/sysutils/eject-1.4.tgz
        NOTE: Be sure to check the file creation date on the package, because
        the version number of the software has not changed.
        3) download a new port skeleton for the eject port from:
        http://www.freebsd.org/ports/
        and use it to rebuild the port.
        4) Use the portcheckout utility to automate option (3) above. The
        portcheckout port is available in /usr/ports/devel/portcheckout or the
        package can be obtained from:
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/devel/portcheckout-2.0.tgz
        ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/devel/portcheckout-2.0.tgz

1559
FreeBSD eject Local Overflow
Local Access Required Input Manipulation
Loss of Integrity

- 漏洞描述

A local overflow exists in eject, a FreeBSD port. The product fails to validate input resulting in a buffer overflow. With a specially crafted request, an attacker can obtain root privileges resulting in a loss of integrity.

- 解决方案

Currently, there are no known upgrades to correct this issue. It is possible to correct the flaw by implementing the following workaround(s): deinstall the eject port/package, if you have installed it, or limit the file permissions on the /usr/local/sbin/eject file (e.g. remove setuid permission, or limit it to a trusted group). Also, FreeBSD has released a patch.
