CVE-2023-3138
Desc: A vulnerability was found in libX11. The security flaw occurs because the
functions in src/InitExt.c in libX11 do not check that the values provided for
the Request, Event, or Error IDs are within the bounds of the arrays that those
functions write to, using those IDs as array indexes. They trust that they were
called with values provided by an Xserver adhering to the bounds specified in
the X11 protocol, as all X servers provided by X.Org do. As the protocol only
specifies a single byte for these values, an out-of-bounds value provided by a
malicious server (or a malicious proxy-in-the-middle) can only overwrite other
portions of the Display structure and not write outside the bounds of the
Display structure itself, possibly causing the client to crash with this memory
corruption.
