Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Qemu versions prior to 2.10.0

Description The issue is related to a memory leak in the io/channel-websock.c component of the QEMU hardware emulator. It can be exploited by a remote attacker to cause a denial of service by triggering slow data-channel read operations.

Recommendations For Qemu versions prior to 2.10.0, update to version 2.10.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the io/channel-websock.c component to minimize the risk of exploitation.
