CVE-2010-4238
Publication date 22 January 2011
Last updated 24 July 2024
Ubuntu priority
The vbd_create function in Xen 3.1.2, when the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 is used, allows guest OS users to cause a denial of service (host OS panic) via an attempted access to a virtual CD-ROM device through the blkback driver. NOTE: some of these details are obtained from third party information.
From the Ubuntu Security Team
Vladymyr Denysov discovered that Xen virtual CD-ROM devices were not handled correctly. A local attacker in a guest could make crafted blkback requests that would crash the host, leading to a denial of service.

Notes
smb
Upstream Xen is more lining up to Xen 4 and I suppose that should handle the CDROM part. So setting not affected. We are not using the kernel part of the xen package, so not-affected.
