Description Petr Matousek 2013-09-12 09:46:43 UTC

A buffer overflow flaw was found in the way qemu processed SCSI REPORT LUNS command when excessive LUNS were defined for a single SCSI target.

A privileged guest user could use this flaw to corrupt qemu process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the qemu process.

Acknowledgements:

This issue was discovered by Asias He of Red Hat.

Comment 2 Petr Matousek 2013-09-12 09:54:39 UTC

Statement:

This issue does not affect the kvm and xen packages as shipped with Red Hat Enterprise Linux 5.

This issue does affect the qemu-kvm package as shipped with Red Hat Enterprise Linux 6. Future qemu-kvm updates in Red Hat Enterprise Linux 6 may address this flaw.
