The X.org project reports:

There is an integer overflow and a double free vulnerability in the way LibX11 handles locales. The integer overflow is a necessary precursor to the double free.

The X.Org project reports:

• Buffer overflows in InitExt.c in libX11 prior to 1.8.6 [CVE-2023-3138]

  The functions in src/InitExt.c in libX11 prior to 1.8.6 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. Instead they trusted that they were called with values provided by an Xserver that was 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. Testing has found it is possible to at least cause the client to crash with this memory corruption.

< 1.8.6,1

The X.org project reports:

XLookupColor() and other X libraries function lack proper validation of the length of their string parameters. If those parameters can be controlled by an external application (for instance a color name that can be emitted via a terminal control sequence) it can lead to the emission of extra X protocol requests to the X server.
