The qemuDomainGetBlockIoTune function in qemu/qemu_driver.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 out-of-bounds read.

The virDomainListPopulate function in conf/domain_conf.c in libvirt before 1.2.9 does not clean up the lock on the list of domains, which allows remote attackers to cause a denial of service (deadlock) via a NULL value in the second parameter in the virConnectListAllDomains API command.

Red Hat libvirt, possibly 0.6.1 through 0.8.2, looks up disk backing stores without referring to the user-defined main disk format, which might allow guest OS users to read arbitrary files on the host OS, and possibly have unspecified other impact, via unknown vectors.

Red Hat libvirt, possibly 0.7.2 through 0.8.2, recurses into disk-image backing stores without extracting the defined disk backing-store format, which might allow guest OS users to read arbitrary files on the host OS, and possibly have unspecified other impact, via unknown vectors.

Red Hat libvirt, possibly 0.6.0 through 0.8.2, creates new images without setting the user-defined backing-store format, which allows guest OS users to read arbitrary files on the host OS via unspecified vectors.

Red Hat libvirt 0.2.0 through 0.8.2 creates iptables rules with improper mappings of privileged source ports, which allows guest OS users to bypass intended access restrictions by leveraging IP address and source-port values, as demonstrated by copying and deleting an NFS directory tree.

Buffer overflow in the proxyReadClientSocket function in proxy/libvirt_proxy.c in libvirt_proxy 0.5.1 might allow local users to gain privileges by sending a portion of the header of a virProxyPacket packet, and then sending the remainder of the packet with crafted values in the header, related to use of uninitialized memory in a validation check.

Multiple methods in libvirt 0.3.2 through 0.5.1 do not check if a connection is read-only, which allows local users to bypass intended access restrictions and perform administrative actions.
