Vulnerabilidades

The vds_installer in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, uses the -k curl parameter when downloading deployUtil.py and vds_bootstrap.py, which prevents SSL certificates from being validated and allows remote attackers to execute arbitrary Python code via a…

Multiple untrusted search path vulnerabilities in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, allow local users to gain privileges via a Trojan horse (1) deployUtil.py or (2) vds_bootstrap.py Python module in /tmp/.

Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, in certain unspecified conditions, does not lock the desktop screen between SPICE sessions, which allows local users with access to a virtual machine to gain access to other users' desktop sessions via unspecified vectors.

The Generic Receive Offload (GRO) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux 5 and 2.6.32 on Red Hat Enterprise Linux 6, as used in Red Hat Enterprise Virtualization (RHEV) Hypervisor and other products, allows remote attackers to cause a denial of service via crafted VLAN packets that are…

Race condition in the SPICE (aka spice-activex) plug-in for Internet Explorer in Red Hat Enterprise Virtualization (RHEV) Manager before 2.2.4 allows local users to create a certain named pipe, and consequently gain privileges, via vectors involving knowledge of the name of this named pipe, in conjunction with use of…

Virtual Desktop Server Manager (VDSM) in Red Hat Enterprise Virtualization (RHEV) 2.2 does not properly accept TCP connections for SSL sessions, which allows remote attackers to cause a denial of service (daemon outage) via crafted SSL traffic.

The subpage MMIO initialization functionality in the subpage_register function in exec.c in QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly select the index for access to the callback array, which allows guest OS users to cause a…

The Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2, and KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via vectors related to instruction emulation.

QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly validate guest QXL driver pointers, which allows guest OS users to cause a denial of service (invalid pointer dereference and guest OS crash) or possibly gain privileges via…

libspice, as used in QEMU-KVM in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and qspice 0.3.0, does not properly restrict the addresses upon which memory-management actions are performed, which allows guest OS users to cause a denial of service (guest OS crash) or possibly gain…

libspice, as used in QEMU-KVM in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and qspice 0.3.0, does not properly validate guest QXL driver pointers, which allows guest OS users to cause a denial of service (invalid pointer dereference and guest OS crash) or possibly gain…

The snapshot merging functionality in Red Hat Enterprise Virtualization Manager (aka RHEV-M) before 2.2 does not properly pass the postzero parameter during operations on deleted volumes, which allows guest OS users to obtain sensitive information by examining the disk blocks associated with a deleted virtual machine.

Virtual Desktop Server Manager (VDSM) in Red Hat Enterprise Virtualization Hypervisor (aka RHEV-H or rhev-hypervisor) before 5.5-2.2 does not properly perform VM post-zeroing after the removal of a virtual machine's data, which allows guest OS users to obtain sensitive information by examining the disk blocks…

Buffer overflow in the jas_stream_printf function in libjasper/base/jas_stream.c in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via vectors related to the mif_hdr_put function and use of vsprintf.
