CVE-2015-7311 | 1 Xen | 1 Xen | 2024-11-21 | 3.6 LOW | N/A |
libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | |||||
CVE-2015-6815 | 7 Arista, Canonical, Fedoraproject and 4 more | 11 Eos, Ubuntu Linux, Fedora and 8 more | 2024-11-21 | 2.7 LOW | 3.5 LOW |
The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors. | |||||
CVE-2015-6654 | 1 Xen | 1 Xen | 2024-11-21 | 2.1 LOW | N/A |
The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest. | |||||
