CVE-2017-12134

The xenbiovecphysmergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability...

linux: Fix Xen block IO merge-ability calculation

ISSUE DESCRIPTION The block layer in Linux may choose to merge adjacent block IO requests. When Linux is running as a Xen guest, the default merging algorithm is replaced with a Xen-specific one. When Linux is running as an x86 PV guest, some BIO's are erroneously merged, corrupting the data stre...

libvirt: qemu: out-of-bounds read access in qemuDomainGetBlockIoTune() due to invalid index

An out-of-bounds read flaw was found in the way libvirt's qemuDomainGetBlockIoTune function looked up the disk index in a non-persistent live disk configuration while a persistent disk configuration was being indexed. A remote attacker able to establish a read-only connection to libvirtd could us...

UBUNTU-CVE-2014-3633

The qemuDomainGetBlockIoTune function in qemu/qemudriver.c in libvirt before 1.2.9, when a disk has been hot-plugged or removed from the live image, allows remote attackers to cause a denial of service crash or read sensitive heap information via a crafted blkiotune query, which triggers an...

qemu: job usage issue in several APIs leading to libvirtd crash

Multiple race conditions in the 1 virDomainBlockStats, 2 virDomainGetBlockInf, 3 qemuDomainBlockJobImpl, and 4 virDomainGetBlockIoTune functions in libvirt before 1.2.1 do not properly verify that the disk is attached, which allows remote read-only attackers to cause a denial of service libvirtd...
