An user able to alter the savevm data (either on the disk or over the wire during migration) could use this flaw to to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. Un usuario capaz de alterar los datos de savevm (ya sea en el disco o por cable durante la migración) podría usar este fallo para corromper la memoria del proceso de QEMU en el host (de destino), lo que potencialmente podría resultar en una ejecución de código arbitraria en el host con los privilegios del proceso QEMU • https://bugzilla.redhat.com/show_bug.cgi?id=1066401 https://security.netapp.com/advisory/ntap-20210727-0002 https://access.redhat.com/security/cve/CVE-2013-4536 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-269: Improper Privilege Management •
