27b9b2f0-8081-11e4-b4ca-bcaec565249c | xserver -- multiple issue with X client request handling
Alan Coopersmith reports:
Ilja van Sprundel, a security researcher with IOActive, has
discovered a large number of issues in the way the X server
code base handles requests from X clients, and has worked
with X.Org's security team to analyze, confirm, and fix
these issues.
The vulnerabilities could be exploited to cause the X server
to access uninitialized memory or overwrite arbitrary memory
in the X server process. This can cause a denial of service
(e.g., an X server segmentation fault), or could be exploited
to achieve arbitrary code execution.
The GLX extension to the X Window System allows an X client
to send X protocol to the X server, to request that the X
server perform OpenGL rendering on behalf of the X client.
This is known as "GLX indirect rendering", as opposed to
"GLX direct rendering" where the X client submits OpenGL
rendering commands directly to the GPU, bypassing the X
server and avoiding the X server code for GLX protocol
handling.
Most GLX indirect rendering implementations share some
common ancestry, dating back to "Sample Implementation"
code from Silicon Graphics, Inc (SGI), which SGI
originally commercially licensed to other Unix workstation
and graphics vendors, and later released as open source, so
those vulnerabilities may affect other licensees of SGI's
code base beyond those running code from the X.Org Foundation
or the XFree86 Project.

54a69cf7-b2ef-11e4-b1f1-bcaec565249c | xorg-server -- Information leak in the XkbSetGeometry request of X servers.
Peter Hutterer reports:
Olivier Fourdan from Red Hat has discovered a protocol handling
issue in the way the X server code base handles the XkbSetGeometry
request.
The issue stems from the server trusting the client to send valid
string lengths in the request data. A malicious client with string
lengths exceeding the request length can cause the server to copy
adjacent memory data into the XKB structs. This data is then
available to the client via the XkbGetGeometry request. The
data length is at least up to 64k, it is possible to obtain
more data by chaining strings, each string length is then
determined by whatever happens to be in that 16-bit region of
memory.
A similarly crafted request can likely cause the X server
to crash.

3c7ba82a-d3fb-11ea-9aba-0c9d925bbbc0 | xorg-server -- Pixel Data Uninitialized Memory Information Disclosure
The X.org project reports:
Allocation for pixmap data in AllocatePixmap() does not initialize
the memory in xserver, it leads to leak uninitialize heap memory to
clients. When the X server runs with elevated privileges.
This flaw can lead to ASLR bypass, which when combined with other
flaws (known/unknown) could lead to lead to privilege elevation in
the client.

out-of-bounds access
The handler for the XIPassiveUngrab request accesses out-of-bounds
memory when invoked with a high keycode or button code.
- CVE-2022-46342/ZDI-CAN-19400: X.Org Server XvdiSelectVideoNotify
use-after-free
The handler for the XvdiSelectVideoNotify request may write to memory
after it has been freed.
- CVE-2022-46343/ZDI-CAN-19404: X.Org Server ScreenSaverSetAttributes
use-after-free
The handler for the ScreenSaverSetAttributes request may write to memory
after it has been freed.
- CVE-2022-46344/ZDI-CAN-19405: X.Org Server XIChangeProperty

xorg-server developers reports:
In the X.Org X server before 2017-06-19, a user authenticated to
an X Session could crash or execute code in the context of the X
Server by exploiting a stack overflow in the endianness conversion
of X Events.
Uninitialized data in endianness conversion in the XEvent handling
of the X.Org X Server before 2017-06-19 allowed authenticated
malicious users to access potentially privileged data from the X
server.
