Denial Of Service (DoS)

qemu-kvm is vulnerable to denial of service DoS attacks. The vulnerability exists through an integer overflow issue in the qcowopen function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service crash via a large L2 table in a QCOW version 1 image...

Privilege Escalation

QEMU-kvm is vulnerable to privilege escalation. An unquoted search path flaw was found in the way the QEMU Guest Agent service installation was performed on Windows. Depending on the permissions of the directories in the unquoted search path, a local unprivileged user could use this flaw to have ...

Information Disclosure

qemu-kvm-rhev is vulnerable to information disclosure attacks. The vulnerability exists as qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, when started in daemon mode, uses weak permissions for certain files, which allows local users to read and write to these files...

Authorization Bypass

qemu-kvm is vulnerable to authorization bypass attacks. The vulnerability exists through a buffer overflow in the SCSI implementation in QEMU, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command...
