## Description

Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in
Xen and possibly other products, allows local users to trigger a heap-based
buffer overflow via certain register values that bypass sanity checks, aka
QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was
inadvertently used by some sources to cover multiple issues that were
labeled "NE2000 network driver and the socket code," but separate
identifiers have been created for the individual vulnerabilities since
there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.
