QEMU NE2000 emulator code execution
| qemu-ne2000-code-execution (38238) |  High Risk |
Description:
QEMU could allow a local attacker to execute arbitrary code on the vulnerable system, caused by an error in the NE2000 emulator. By writing an overly large Ethernet frame, a local attacker could exploit this vulnerability to possibly cause a heap-based buffer overflow and execute arbitrary code on the vulnerable system.
