FreeBSD : qemu -- unchecked block read/write vulnerability (9cfbca7f-efb7-11dc-be01-0211060005df)

medium Nessus Plugin ID 31437

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Ian Jackson reports on the debian-security mailinglist :

When a block device read or write request is made by the guest, nothing checks that the request is within the range supported by the backend, but the code in the backend typically assumes that the request is sensible.

Depending on the backend, this can allow the guest to read and write arbitrary memory locations in qemu, and possibly gain control over the qemu process, escaping from the emulation/virtualisation.

Solution

Update the affected packages.
