NOTE: this vulnerability exists because an incomplete fix for CVE-2007-1320. CVE-2015-3209 Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. CVE-2015-5165 The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. CVE-2015-5279 Heap-based buffer overflow in the ne2000_receive function in hw/net/ne2000.c in QEMU before 188.8.131.52 allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via vectors related to receiving packets. CVE-2015-7504 - reserved A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user (with the CAP_SYS_RAWIO capability) inside a guest could use this flaw to crash the host QEMU process (resulting in denial of service) or, potentially, execute arbitrary code with privileges of the host QEMU process. CVE-2015-7512 Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet. Impact An attacker may be able to cause a denial-of-service (DoS) or execute arbitrary code via various means. Security Issue Status F5 Product Development has assigned ID 572590, 572592, 572596, 572597, and 572599 (BIG-IP) to this vulnerability, and has evaluated the currently supported releases for potential vulnerability.
