Description Preview
The vulnerability in QEMU 1.x before 1.7.2 is due to an integer signedness error in the virtio_net_load function in hw/net/virtio-net.c. An attacker could exploit this flaw by sending a specially crafted savevm image to the vulnerable system, leading to a buffer overflow condition. Successful exploitation of this vulnerability could allow the attacker to execute arbitrary code on the target system.
Overview
This CVE describes an integer signedness error in QEMU 1.x before version 1.7.2, which could be exploited by remote attackers to execute arbitrary code via a crafted savevm image, resulting in a buffer overflow.
Remediation
To remediate this vulnerability, users are advised to update their QEMU software to version 1.7.2 or later. It is recommended to apply the necessary patches provided by the vendor to address the integer signedness error in the virtio_net_load function. Additionally, users should ensure that all systems running QEMU are regularly updated with the latest security patches to mitigate the risk of exploitation.
