COMPLETE Summary
The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors.
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

(bnc#813677) XSA-46: CVE-2013-1919: Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to 'passed-through IRQs or PCI devices.' (bnc#813675) XSA-45: CVE-2013-1918: Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to 'deep page table traversal.' (bnc#816159) XSA-44: CVE-2013-1917: Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. (bnc#813673) XSA-41: CVE-2012-6075: Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet. (bnc#797523) XSA-37: CVE-2013-0154: The get_page_type function in xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled, allows local PV or HVM guest administrators to cause a denial of service (assertion failure and hypervisor crash) via unspecified vectors related to a hypercall. (bnc#797031) XSA-36: CVE-2013-0153: The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. (bnc#800275) XSA-33: CVE-2012-5634: Xen 4.2.x, 4.1.x, and 4.0, when using Intel VT-d for PCI passthrough, does not properly configure VT-d when supporting a device that is behind a legacy PCI Bridge, which allows local guests to cause a denial of service to other guests by injecting an interrupt. (bnc#794316) XSA-31: CVE-2012-5515: The (1) XENMEM_decrease_reservation, (2) XENMEM_populate_physmap, and (3) XENMEM_exchange hypercalls in Xen 4.2 and earlier allow local guest administrators to cause a denial of service (long loop and hang) via a crafted extent_order value. (bnc#789950) XSA-30: CVE-2012-5514: The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a denial of service (hang) via unspecified vectors. (bnc#789948) XSA-29: CVE-2012-5513: The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range. (bnc#789951) XSA-27: CVE-2012-6333: Multiple HVM control operations in Xen 3.4 through 4.2 allow local HVM guest OS administrators to cause a denial of service (physical CPU consumption) via a large input. (bnc#789944) XSA-27: CVE-2012-5511: Stack-based buffer overflow in the dirty video RAM tracking functionality in Xen 3.4 through 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) via a large bitmap image. (bnc#789944) XSA-26: CVE-2012-5510: Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the tracking list when freeing the page, which allows local guest OS administrators to cause a denial of service (hypervisor crash) via unspecified vectors. (bnc#789945) XSA-25: CVE-2012-4544: The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk. (bnc#787163) XSA-24: CVE-2012-4539: Xen 4.0 through 4.2, when running 32-bit x86 PV guests on 64-bit hypervisors, allows local guest OS administrators to cause a denial of service (infinite loop and hang or crash) via invalid arguments to GNTTABOP_get_status_frames, aka 'Grant table hypercall infinite loop DoS vulnerability.' (bnc#786520) XSA-23: CVE-2012-4538: The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors. (bnc#786519) XSA-22: CVE-2012-4537: Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka 'Memory mapping failure DoS vulnerability.' (bnc#786517) XSA-20: CVE-2012-4535: Xen 3.4 through 4.2, and possibly earlier versions, allows local guest OS administrators to cause a denial of service (Xen infinite loop and physical CPU consumption) by setting a VCPU with an 'inappropriate deadline.' (bnc#786516) XSA-19: CVE-2012-4411: The graphical console in Xen 4.0, 4.1 and 4.2 allows local OS guest administrators to obtain sensitive host resource information via the qemu monitor. NOTE: this might be a duplicate of CVE-2007-0998. (bnc#779212) XSA-15: CVE-2012-3497: (1) TMEMC_SAVE_GET_CLIENT_WEIGHT, (2) TMEMC_SAVE_GET_CLIENT_CAP, (3) TMEMC_SAVE_GET_CLIENT_FLAGS and (4) TMEMC_SAVE_END in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (NULL pointer dereference or memory corruption and host crash) or possibly have other unspecified impacts via a NULL client id. (bnc#777890) Also the following non-security bugs have been fixed : - xen hot plug attach/detach fails modified blktap-pv-cdrom.patch. (bnc#805094) - guest 'disappears' after live migration Updated block-dmmd script.

We disable these checks when building in a stub domain for pvgrub since this uses the guest's own memory and is isolated. Decompression of gzip compressed kernels and ramdisks has been safe since 14954:58205257517d (Xen 3.1.0 onwards). This is XSA-25 / CVE-2012-4544. Also make explicit checks for buffer overflows in various decompression routines. These were already ruled out due to other properties of the code but check them as a belt-and-braces measure. [ Includes 25589:60f09d1ab1fe for CVE-2012-2625] (CVE-2012-4544) - compat/gnttab: Prevent infinite loop in compat code c/s 20281:95ea2052b41b, which introduces Grant Table version 2 hypercalls introduces a vulnerability whereby the compat hypercall handler can fall into an infinite loop. If the watchdog is enabled, Xen will die after the timeout. This is a security problem, XSA-24 / CVE-2012-4539. (CVE-2012-4539) - xen/mm/shadow: check toplevel pagetables are present before unhooking them. If the guest has not fully populated its top-level PAE entries when it calls HVMOP_pagetable_dying, the shadow code could try to unhook entries from MFN 0. Add a check to avoid that case. This issue was introduced by c/s 21239:b9d2db109cf5. This is a security problem, XSA-23 / CVE-2012-4538. (CVE-2012-4538) - x86/physmap: Prevent incorrect updates of m2p mappings In certain conditions, such as low memory, set_p2m_entry can fail. Currently, the p2m and m2p tables will get out of sync because we still update the m2p table after the p2m update has failed. If that happens, subsequent guest-invoked memory operations can cause BUGs and ASSERTs to kill Xen. This is fixed by only updating the m2p table iff the p2m was successfully updated. This is a security problem, XSA-22 / CVE-2012-4537. (CVE-2012-4537) - x86/physdev: Range check pirq parameter from guests Otherwise Xen will read beyond either end of the struct domain.arch.pirq_emuirq array, usually resulting in a fatal page fault. This vulnerability was introduced by c/s 23241:d21100f1d00e, which adds a call to domain_pirq_to_emuirq which uses the guest provided pirq value before range checking it, and was fixed by c/s 23573:584c2e5e03d9 which changed the behaviour of the domain_pirq_to_emuirq macro to use radix trees instead of a flat array. This is XSA-21 / CVE-2012-4536. (CVE-2012-4536) - VCPU/timers: Prevent overflow in calculations, leading to DoS vulnerability The timer action for a vcpu periodic timer is to calculate the next expiry time, and to reinsert itself into the timer queue. If the deadline ends up in the past, Xen never leaves __do_softirq. The affected PCPU will stay in an infinite loop until Xen is killed by the watchdog (if enabled). This is a security problem, XSA-20 / CVE-2012-4535. (CVE-2012-4535) - Correct RTC time offset update error for HVM guest changeset 24947:b198ada9689d - always release vm running lock on VM shutdown Before this patch, when xend restarted, the VM running lock will not be released on shutdown, so the VM could never start again.

One of the issue (CVE-2012-5513 ) could even lead to privilege escalation from guest to host. Some of the recently published Xen Security Advisories ( XSA 25and 28) are not fixed by this update and should be fixed in a future release. - CVE-2011-3131 ( XSA 5): DoS using I/OMMU faults from PCI-passthrough guest A VM that controls a PCI[E] device directly can cause it to issue DMA requests to invalid addresses. Although these requests are denied by the I/OMMU, the hypervisor needs to handle the interrupt and clear the error from the I/OMMU, and this can be used to live-lock a CPU and potentially hang the host. - CVE-2012-4535 ( XSA 20): Timer overflow DoS vulnerability A guest which sets a VCPU with an inappropriate deadline can cause an infinite loop in Xen, blocking the affected physical CPU indefinitely. - CVE-2012-4537 ( XSA 22): Memory mapping failure DoS vulnerability When set_p2m_entry fails, Xen last seen 2020-03-17 modified 2012-12-09 plugin id 63188 published 2012-12-09 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/63188 title Debian DSA-2582-1 : xen - several vulnerabilities NASL family OracleVM Local Security Checks NASL id ORACLEVM_OVMSA-2012-0050.NASL description The remote OracleVM system is missing necessary patches to address critical security updates : - compat/gnttab: Prevent infinite loop in compat code c/s 20281:95ea2052b41b, which introduces Grant Table version 2 hypercalls introduces a vulnerability whereby the compat hypercall handler can fall into an infinite loop. If the watchdog is enabled, Xen will die after the timeout. This is a security problem, XSA-24 / CVE-2012-4539. (CVE-2012-4539) - xen/mm/shadow: check toplevel pagetables are present before unhooking them. If the guest has not fully populated its top-level PAE entries when it calls HVMOP_pagetable_dying, the shadow code could try to unhook entries from MFN 0. Add a check to avoid that case. This issue was introduced by c/s 21239:b9d2db109cf5. This is a security problem, XSA-23 / CVE-2012-4538. (CVE-2012-4538) - x86/physmap: Prevent incorrect updates of m2p mappings In certain conditions, such as low memory, set_p2m_entry can fail. Currently, the p2m and m2p tables will get out of sync because we still update the m2p table after the p2m update has failed. If that happens, subsequent guest-invoked memory operations can cause BUGs and ASSERTs to kill Xen. This is fixed by only updating the m2p table iff the p2m was successfully updated. This is a security problem, XSA-22 / CVE-2012-4537. (CVE-2012-4537) - VCPU/timers: Prevent overflow in calculations, leading to DoS vulnerability The timer action for a vcpu periodic timer is to calculate the next expiry time, and to reinsert itself into the timer queue. If the deadline ends up in the past, Xen never leaves __do_softirq. The affected PCPU will stay in an infinite loop until Xen is killed by the watchdog (if enabled). This is a security problem, XSA-20 / CVE-2012-4535. (CVE-2012-4535) - always release vm running lock on VM shutdown Before this patch, when xend restarted, the VM running lock will not be released on shutdown, so the VM could never start again. Talked with Junjie, we recommend always releasing the lock on VM shutdown. So even when xend restarted, there should be no stale lock leaving there. - Xen Security Advisory CVE-2012-4411 / XSA-19 version 2 guest administrator can access qemu monitor console Disable qemu monitor by default. The qemu monitor is an overly powerful feature which must be protected from untrusted (guest) administrators.
