Description
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.
The vulnerability exists in Quick Emulator (QEMU) configured with network block device (NBD) client support due to improper processing of an NBD server's response to an NBD_OPT_LIST request sent from an affected NBD client. A remote attacker can trick the user on an NBD client into sending an NBD_OPT_LIST request to the attacker-controlled NBD serverб trigger stack-based buffer overflow and cause the service to crash or execute arbitrary code on the targeted NBD client with elevated privileges.
Remediation
Update to version 2.9 or later.
