Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2013-4148)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Integer signedness error in the virtio_net_load function in hw/net/virtio-net.c in QEMU 1.x before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image, which triggers a buffer overflow.


2) Buffer overflow (CVE-ID: CVE-2013-4149)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Buffer overflow in virtio_net_load function in net/virtio-net.c in QEMU 1.3.0 through 1.7.x before 1.7.2 might allow remote attackers to execute arbitrary code via a large MAC table.


3) Buffer overflow (CVE-ID: CVE-2013-4150)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The virtio_net_load function in hw/net/virtio-net.c in QEMU 1.5.0 through 1.7.x before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors in which the value of curr_queues is greater than max_queues, which triggers an out-of-bounds write.


4) Code Injection (CVE-ID: CVE-2013-4151)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The virtio_load function in virtio/virtio.c in QEMU 1.x before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image, which triggers an out-of-bounds write.
