Description:

CVE (CAN) ID: CVE-2015-7504

QEMU is an open source simulator software.

The Qemu of the amd pc-Net II Ethernet Controller is enabled with the heap buffer overflow vulnerability. When receiving data packets in the send-back mode, the CRC code is appended to the receiving buffer. If the size of the received data is equal to the size of the receiving buffer, the attached CRC code overwrites four bytes outside the's-> buffer array, causing the Qemu instance to crash, resulting in DOS and even arbitrary code execution.
