Subject: qemu: CVE-2011-3346

CVE-2011-3346 qemu: local DoS with SCSI CD-ROM

Paolo Bonzini of Red Hat found a buffer overflow in QEMU's SCSI
subsystem. hw/scsi-disk.c tries to zero a user-provided number of
bytes in a fixed-size buffer. An unprivileged local guest user
can potentially use this flaw to crash the guest.
