An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service.
An integer underflow issue was found in the QEMU built-in VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service.
Отчет
Red Hat Enterprise Linux 6, 7 and RHEL Advanced Virtualization are not affected by this flaw as they did not include support for the extended clipboard pseudo-encoding (upstream commit 0bf41cab).
