| CVE-2010-4238 | 3 Citrix, Linux, Redhat | 3 Xen, Linux Kernel, Enterprise Linux | 2023-02-12 | 5.5 MEDIUM | N/A |
| The vbd_create function in Xen 3.1.2, when the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 is used, allows guest OS users to cause a denial of service (host OS panic) via an attempted access to a virtual CD-ROM device through the blkback driver. NOTE: some of these details are obtained from third party information. | |||||
| CVE-2010-4247 | 2 Citrix, Linux | 2 Xen, Linux Kernel | 2023-02-12 | 5.5 MEDIUM | N/A |
| The do_block_io_op function in (1) drivers/xen/blkback/blkback.c and (2) drivers/xen/blktap/blktap.c in Xen before 3.4.0 for the Linux kernel 2.6.18, and possibly other versions, allows guest OS users to cause a denial of service (infinite loop and CPU consumption) via a large production request index to the blkback or blktap back-end drivers. NOTE: some of these details are obtained from third party information. | |||||
| CVE-2010-4255 | 1 Citrix | 1 Xen | 2018-10-10 | 6.1 MEDIUM | N/A |
| The fixup_page_fault function in arch/x86/traps.c in Xen 4.0.1 and earlier on 64-bit platforms, when paravirtualization is enabled, does not verify that kernel mode is used to call the handle_gdt_ldt_mapping_fault function, which allows guest OS users to cause a denial of service (host OS BUG_ON) via a crafted memory access. | |||||
| CVE-2010-3699 | 1 Citrix | 1 Xen | 2018-10-10 | 2.7 LOW | N/A |
| The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly, related to (1) netback, (2) blkback, or (3) blktap. | |||||
| CVE-2008-4405 | 1 Citrix | 1 Xen | 2017-09-28 | 7.2 HIGH | N/A |
| xend in Xen 3.0.3 does not properly limit the contents of the /local/domain xenstore directory tree, and does not properly restrict a guest VM's write access within this tree, which allows guest OS users to cause a denial of service and possibly have unspecified other impact by writing to (1) console/tty, (2) console/limit, or (3) image/device-model-pid. NOTE: this issue was originally reported as an issue in libvirt 0.3.3 and xenstore, but CVE is considering the core issue to be related to Xen. | |||||
| CVE-2011-3262 | 1 Citrix | 1 Xen | 2017-08-28 | 2.1 LOW | N/A |
| tools/libxc/xc_dom_bzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allows local users to cause a denial of service (management software infinite loop and management domain resource consumption) via unspecified vectors related to "Lack of error checking in the decompression loop." | |||||
| CVE-2008-5716 | 1 Citrix | 1 Xen | 2017-08-07 | 7.2 HIGH | N/A |
| xend in Xen 3.3.0 does not properly restrict a guest VM's write access within the /local/domain xenstore directory tree, which allows guest OS users to cause a denial of service and possibly have unspecified other impact by writing to (1) console/tty, (2) console/limit, or (3) image/device-model-pid. NOTE: this issue exists because of erroneous set_permissions calls in the fix for CVE-2008-4405. | |||||
| CVE-2011-1898 | 1 Citrix | 1 Xen | 2011-10-25 | 7.4 HIGH | N/A |
| Xen 4.1 before 4.1.1 and 4.0 before 4.0.2, when using PCI passthrough on Intel VT-d chipsets that do not have interrupt remapping, allows guest OS users to gain host OS privileges by "using DMA to generate MSI interrupts by writing to the interrupt injection registers." | |||||
| CVE-2011-1583 | 1 Citrix | 1 Xen | 2011-08-23 | 6.9 MEDIUM | N/A |
| Multiple integer overflows in tools/libxc/xc_dom_bzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allow local users to cause a denial of service and possibly execute arbitrary code via a crafted paravirtualised guest kernel image that triggers (1) a buffer overflow during a decompression loop or (2) an out-of-bounds read in the loader involving unspecified length fields. | |||||
