[Ubuntu-x-swat] [Bug 972324] Re: server fails to start up if TMPDIR is set to something on a different filesystem from /var/lib/xkb

2013-03-25 Thread Alec Warner
There may also exist a security issue, where user alice creates
specially crafted keymaps in /tmp/$HASH.xkm and then user bob launched X
and the X system tries to re-use alice's evil keymap.

I'm unsure if the X server keymap loader is exploitable, but it is
likely that keymaps should not be shared between users in this way (if
nothing else, alice can upload a wacky keymap and bob may not know how
to turn it off.)

[Ubuntu-x-swat] [Bug 933745] [NEW] Xvfb: any use of the XInput extension causes Xvfb to crash

2012-02-16 Thread Alec Warner
Public bug reported:

Repro steps:
* Run Xvfb -ac :99 in a terminal
* Run DISPLAY=:99 xinput list in a second terminal

Expected:
List of input devices appears (XTest, core). Xvfb continues to run.

Actual:
Xvfb segfaults in first terminal.

This problem affects any user of Xvfb who tries to run a client that
uses the XInput extension.  For example, a user runs a new desktop
session, and a session program tries to enumerate the XInput devices (or
the user has a startup script containing any xinput commands).

There is an upstream patch which I've verified fixes the problem: 
http://cgit.freedesktop.org/xorg/xserver/commit/hw/vfb/InitInput.c?id=0e7703f9b1927328954a2fc87aac6be244819329
The version of Xorg/Xvfb in Precise has this patch (from inspection of the 
source tarball for xvfb package).

We'd like this to be backported to Lucid
