CVE-2013-4531
HighSummary
Buffer overflow in target-arm/machine.c in QEMU before version 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a negative value in cpreg_vmstate_array_len in a savevm image.
Risk Assessment
This vulnerability can lead to significant disruptions in system operation and allow attackers to execute code remotely, posing a serious security threat to the organization.
Recommendation
It is recommended to update QEMU to version 1.7.2 or later to mitigate this vulnerability and reduce the risk associated with attacks.
