X.org and some X.org libraries: Local privilege escalations

X.org and some X.org libraries: Local privilege escalations X.org, libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm are vulnerable to local privilege escalations because of unchecked setuid() calls. xorg-x11,xorg-server,xtrans,xload,xinit,xterm,xf86dga,xdm,libX11 2006-08-28 2006-12-13 135974 local 1.0.4-r1 1.0.4-r1 1.0.2-r6 1.0.2-r6 1.0.1-r1 1.0.1-r1 1.0.1-r1 1.0.1-r1 6.8.2-r8 6.9.0-r2 6.9.0-r2 1.0.2-r6 1.1.0-r1 1.1.0-r1 1.0.1-r1 1.0.1-r1 1.0.0-r1 1.0.0-r1 215 215 7.0-r2 7.0-r2

X.org is an implementation of the X Window System.

Several X.org libraries and X.org itself contain system calls to set*uid() functions, without checking their result.

Local users could deliberately exceed their assigned resource limits and elevate their privileges after an unsuccessful set*uid() system call. This requires resource limits to be enabled on the machine.

There is no known workaround at this time.

All X.Org xdm users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-apps/xdm-1.0.4-r1"

All X.Org xinit users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-apps/xinit-1.0.2-r6"

All X.Org xload users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-apps/xload-1.0.1-r1"

All X.Org xf86dga users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-apps/xf86dga-1.0.1-r1"

All X.Org users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.9.0-r2"

All X.Org X servers users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-base/xorg-server-1.1.0-r1"

All X.Org X11 library users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/libx11-1.0.1-r1"

All X.Org xtrans library users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/xtrans-1.0.1-r1"

All xterm users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-terms/xterm-215"

All users of the X11R6 libraries for emulation of 32bit x86 on amd64 should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-emulation/emul-linux-x86-xlibs-7.0-r2"

Please note that the fixed packages have been available for most architectures since June 30th but the GLSA release was held up waiting for the remaining architectures.
