Description Mark J. Cox 2003-05-19 08:31:53 UTC

There are a number of vulnerabilities that affect the version of XFree86
supplied with Enterprise Linux.  An update, RHSA-2003:065, is being worked on
and packages available for QA this week.

CAN-2002-0164
        A vulnerability in the MIT-SHM extension of the X server allows
        local users to read and write arbitrary shared memory, to
        cause a denial of service or gain privileges.  Fixed, but it was an    
        incomplete fix - for the case where the X server is started
        from xdm which was not handled.  A more complete patch was
        made available.

CAN-2002-1510
        XDM restrictions bypassed by non existent directory
        http://www.xfree86.org/pipermail/cvs-commit/2001-October/003140.html

        It is fixed in the upstream 4.2.0 tarball

CAN-2003-0063
        xterm contains escape sequence to report current window title.

CAN-2003-0071
        Possible to lock up xterm with corrupt DEC UDK sequence, Thomas
        Dickey says it affects all versions, my initial analysis was
        wrong
