Denial Of Service (DoS)

libX11.so is vulnerable to Denial Of Service DoS. The vulnerability exists due to a memory corruption in multiple functions of src/InitExt.c because they do not check array limits properly causing an out-of-bounds which allows an attacker to crash the application...

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.
