Title
Spice-server: spice: heap oob read/write via unchecked migration data offsets
Summary
A flaw was found in spice-server. Multiple migration data handlers use client-supplied offsets from SPICE_MSGC_MIGRATE_DATA messages without bounds validation, allowing a malicious authenticated SPICE client during VM live migration to read arbitrary heap memory or trigger heap corruption via out-of-bounds read and write operations on the message buffer.
