QEMU (Quick Emulator) is a set of emulation processor software from Fabrice Bellard, a French personal developer. QEMU VNC server has a denial of service vulnerability, which stems from an integer underflow in the processing of ClientCutText messages in extended format, which can be exploited by an attacker to make QEMU unresponsive by sending specially crafted payload messages, resulting in a denial of service.
