Secunia reports:

A vulnerability has been reported in QEMU, which can be exploited by malicious, local users to bypass certain security restrictions.

The vulnerability is caused due to the "drive_init()" function in vl.c determining the format of a disk from data contained in the disk's header. This can be exploited by a malicious user in a guest system to e.g. read arbitrary files on the host by writing a fake header to a raw formatted disk image.
