Doc Text: |
An out-of-bound write access flaw was found in the way QEMU loads ROM contents at boot time. This flaw occurs in the rom_copy() routine while loading the contents of a 32-bit -kernel image into memory. Running an untrusted -kernel image may load contents at arbitrary memory locations, potentially leading to code execution with the privileges of the QEMU process.
