Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU disk image utility’s ‘info’ command. A specially crafted image file containing a json: value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, resulting in denial of service or issues with...

OpenStack Cinder, Glance, and Nova contain Uncontrolled Resource Consumption

The image parser in OpenStack Cinder prior to 7.0.2, and 8.0.0 and above, prior to 9.0.0; Glance prior to 14.00; and Nova prior to 12.0.4 does not properly limit qemu-img calls, which might allow attackers to cause a denial of service memory and disk consumption via a crafted disk image. This iss...

openstack-nova-compute: Arbitrary Host File Overwrite via Unconstrained qemu-img Format Handling in OpenStack Nova

A flaw in OpenStack Nova’s interaction with the qemu-img utility allows an authenticated user to overwrite arbitrary files on the compute host. This occurs because Nova invokes qemu-img without strictly constraining the disk image format, enabling a malicious user to craft a QCOW2 header on a raw...
