AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions QEMU versions prior to 2.5.1

Description The issue allows local guest OS administrators to cause a denial of service, resulting in an infinite loop and QEMU process crash. This is achieved by providing crafted values for the PSTART and PSTOP registers, which are involved in ring buffer control.

Recommendations For versions prior to 2.5.1, update to version 2.5.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the NE2000 NIC emulation support to minimize the risk of exploitation.
