| Doc Text: |
A flaw was found in libXi. An out-of-bounds read vulnerability in the X Input 2 (XI2) class parser allows a malicious X server to cause a Denial of Service (DoS) by crashing connected client applications. When an application receives and processes specially crafted input from the server, insufficient boundary checking causes the client to read beyond memory limits and terminate unexpectedly.
