    description The SUSE Linux Enterprise 10 Service Pack 3 LTSS Xen hypervisor and toolset have been updated to fix various security issues : The following security issues have been addressed : 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-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-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-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-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-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-47: CVE-2013-1920: Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running 'under memory pressure' and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors. (bnc#813677) XSA-55: CVE-2013-2196: Multiple unspecified vulnerabilities in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to 'other problems' that are not CVE-2013-2194 or CVE-2013-2195. (bnc#823011) XSA-55: CVE-2013-2195: The Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to 'pointer dereferences' involving unexpected calculations. (bnc#823011) XSA-55: CVE-2013-2194: Multiple integer overflows in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel. (bnc#823011) XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. (bnc#840592) XSA-67: CVE-2013-4368: The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. (bnc#842511) XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. (bnc#848657) XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. (bnc#849668) XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue. (bnc#853049) Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id ORACLEVM_OVMSA-2012-0056.NASL
    description The remote OracleVM system is missing necessary patches to address critical security updates : - xen: fix error handling of guest_physmap_mark_populate_on_demand The only user of the 'out' label bypasses a necessary unlock, thus enabling the caller to lock up Xen. Also, the function was never meant to be called by a guest for itself, so rather than inspecting the code paths in depth for potential other problems this might cause, and adjusting e.g. the non-guest printk in the above error path, just disallow the guest access to it. Finally, the printk (considering its potential of spamming the log, the more that it's not using XENLOG_GUEST), is being converted to P2M_DEBUG, as debugging is what it apparently was added for in the first place. This is XSA-30 / CVE-2012-5514. (CVE-2012-5514) - Revert version 2 of XSA-30 / CVE-2012-5514 (CVE-2012-5514) - memop: limit guest specified extent order Allowing unbounded order values here causes almost unbounded loops and/or partially incomplete requests, particularly in PoD code. The added range checks in populate_physmap, decrease_reservation, and the 'in' one in memory_exchange architecturally all could use PADDR_BITS - PAGE_SHIFT, and are being artificially constrained to MAX_ORDER. This is XSA-31 / CVE-2012-5515. (CVE-2012-5515) - xen: fix error path of guest_physmap_mark_populate_on_demand The only user of the 'out' label bypasses a necessary unlock, thus enabling the caller to lock up Xen. This is XSA-30 / CVE-2012-5514. (CVE-2012-5514) - xen: add missing guest address range checks to XENMEM_exchange handlers Ever since its existence (3.0.3 iirc) the handler for this has been using non address range checking guest memory accessors (i.e. the ones prefixed with two underscores) without first range checking the accessed space (via guest_handle_okay), allowing a guest to access and overwrite hypervisor memory. This is XSA-29 / CVE-2012-5513. - hvm: Limit the size of large HVM op batches Doing large p2m updates for HVMOP_track_dirty_vram without preemption ties up the physical processor. Integrating preemption into the p2m updates is hard so simply limit to 1GB which is sufficient for a 15000 * 15000 * 32bpp framebuffer. For HVMOP_modified_memory and HVMOP_set_mem_type preemptible add the necessary machinery to handle preemption. This is CVE-2012-5511 / XSA-27. x86/paging: Don't allocate user-controlled amounts of stack memory. This is XSA-27 / CVE-2012-5511. v2: Provide definition of GB to fix x86-32 compile. - xen/common/grant_table.c gnttab: fix releasing of memory upon switches between versions gnttab_unpopulate_status_frames incompletely freed the pages previously used as status frame in that they did not get removed from the domain's xenpage_list, thus causing subsequent list corruption when those pages did get allocated again for the same or another purpose. Similarly, grant_table_create and gnttab_grow_table both improperly clean up in the event of an error - pages already shared with the guest can't be freed by just passing them to free_xenheap_page. Fix this by sharing the pages only after all allocations succeeded. This is CVE-2012-5510 / XSA-26. (CVE-2012-5510)

    description Updated kernel packages that fix three security issues and several bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * It was found that the Xen hypervisor implementation did not perform range checking on the guest provided values in multiple hypercalls. A privileged guest user could use this flaw to trigger long loops, leading to a denial of service (Xen hypervisor hang). (CVE-2012-5515, Moderate) * It was found that when running a 32-bit binary that uses a large number of shared libraries, one of the libraries would always be loaded at a predictable address in memory. An attacker could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2012-1568, Low) * A flaw was found in the way the Linux kernel's IPv6 implementation handled overlapping, fragmented IPv6 packets. A remote attacker could potentially use this flaw to bypass protection mechanisms (such as a firewall or intrusion detection system (IDS)) when sending network packets to a target system. (CVE-2012-4444, Low) Red Hat would like to thank the Xen project for reporting CVE-2012-5515, and Antonios Atlasis working with Beyond Security's SecuriTeam Secure Disclosure program and Loganaden Velvindron of AFRINIC for reporting CVE-2012-4444. This update also fixes several bugs. Space precludes documenting all of these changes in this advisory. Documentation for these changes will be available shortly from the Red Hat Enterprise Linux 5.9 Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description Multiple denial of service vulnerabilities have been discovered in the Xen Hypervisor. 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's internal data structures (the p2m and m2p tables) can get out of sync. This failure can be triggered by unusual guest behaviour exhausting the memory reserved for the p2m table. If it happens, subsequent guest-invoked memory operations can cause Xen to fail an assertion and crash. - CVE-2012-4538 ( XSA 23): Unhooking empty PAE entries DoS vulnerability The HVMOP_pagetable_dying hypercall does not correctly check the caller's pagetable state, leading to a hypervisor crash. - CVE-2012-4539 ( XSA 24): Grant table hypercall infinite loop DoS vulnerability Due to inappropriate duplicate use of the same loop control variable, passing bad arguments to GNTTABOP_get_status_frames can cause an infinite loop in the compat hypercall handler. - CVE-2012-5510 ( XSA 26): Grant table version switch list corruption vulnerability Downgrading the grant table version of a guest involves freeing its status pages. This freeing was incomplete - the page(s) are freed back to the allocator, but not removed from the domain's tracking list. This would cause list corruption, eventually leading to a hypervisor crash. - CVE-2012-5513 ( XSA 29): XENMEM_exchange may overwrite hypervisor memory The handler for XENMEM_exchange accesses guest memory without range checking the guest provided addresses, thus allowing these accesses to include the hypervisor reserved range. A malicious guest administrator can cause Xen to crash. If the out of address space bounds access does not lead to a crash, a carefully crafted privilege escalation cannot be excluded, even though the guest doesn't itself control the values written. - CVE-2012-5514 ( XSA 30): Broken error handling in guest_physmap_mark_populate_on_demand() guest_physmap_mark_populate_on_demand(), before carrying out its actual operation, checks that the subject GFNs are not in use. If that check fails, the code prints a message and bypasses the gfn_unlock() matching the gfn_lock() carried out before entering the loop. A malicious guest administrator can then use it to cause Xen to hang. - CVE-2012-5515 ( XSA 31): Several memory hypercall operations allow invalid extent order values Allowing arbitrary extent_order input values for XENMEM_decrease_reservation, XENMEM_populate_physmap, and XENMEM_exchange can cause arbitrarily long time being spent in loops without allowing vital other code to get a chance to execute. This may also cause inconsistent state resulting at the completion of these hypercalls.

    description The SUSE Linux Enterprise Server 11 Service Pack 1 LTSS Xen hypervisor and toolset have been updated to fix various security issues and some bugs. The following security issues have been addressed : XSA-84: CVE-2014-1894: Xen 3.2 (and presumably earlier) exhibit both problems with the overflow issue being present for more than just the suboperations listed above. (bnc#860163) XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through 4.1, while not affected by the above overflow, have a different overflow issue on FLASK_{GET,SET}BOOL and expose unreasonably large memory allocation to arbitrary guests. (bnc#860163) XSA-84: CVE-2014-1891: The FLASK_{GET,SET}BOOL, FLASK_USER and FLASK_CONTEXT_TO_SID suboperations of the flask hypercall are vulnerable to an integer overflow on the input size. The hypercalls attempt to allocate a buffer which is 1 larger than this size and is therefore vulnerable to integer overflow and an attempt to allocate then access a zero byte buffer. (bnc#860163) XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue. (bnc#853049) XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. (bnc#849668) XSA-74: CVE-2013-4553: The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). (bnc#849667) XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. (bnc#848657) XSA-67: CVE-2013-4368: The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. (bnc#842511) XSA-66: CVE-2013-4361: The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction. (bnc#841766) XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. (bnc#840592) XSA-62: CVE-2013-1442: Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain sensitive information by reading the registers. (bnc#839596) XSA-61: CVE-2013-4329: The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction. (bnc#839618) XSA-60: CVE-2013-2212: The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling chaches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. (bnc#831120) XSA-58: 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#826882) XSA-58: CVE-2013-1432: Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possible gain privileges via unspecified vectors. (bnc#826882) XSA-57: CVE-2013-2211: The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors. (bnc#823608) XSA-56: CVE-2013-2072: Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap. (bnc#819416) XSA-55: CVE-2013-2196: Multiple unspecified vulnerabilities in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to 'other problems' that are not CVE-2013-2194 or CVE-2013-2195. (bnc#823011) XSA-55: CVE-2013-2195: The Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to 'pointer dereferences' involving unexpected calculations. (bnc#823011) XSA-55: CVE-2013-2194: Multiple integer overflows in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel. (bnc#823011) XSA-53: CVE-2013-2077: Xen 4.0.x, 4.1.x, and 4.2.x does not properly restrict the contents of a XRSTOR, which allows local PV guest users to cause a denial of service (unhandled exception and hypervisor crash) via unspecified vectors. (bnc#820919) XSA-52: CVE-2013-2076: Xen 4.0.x, 4.1.x, and 4.2.x, when running on AMD64 processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one domain to determine portions of the state of floating point instructions of other domains, which can be leveraged to obtain sensitive information such as cryptographic keys, a similar vulnerability to CVE-2006-1056. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels. (bnc#820917) XSA-50: CVE-2013-1964: Xen 4.0.x and 4.1.x incorrectly releases a grant reference when releasing a non-v1, non-transitive grant, which allows local guest administrators to cause a denial of service (host crash), obtain sensitive information, or possible have other impacts via unspecified vectors. (bnc#816156) XSA-49: CVE-2013-1952: Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service (interrupt injection) via unspecified vectors. (bnc#816163) XSA-47: CVE-2013-1920: Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running 'under memory pressure' and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors. (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.

    title SUSE SLES11 Security Update : Xen (SUSE-SU-2014:0446-1)
  • NASL family SuSE Local Security Checks
    NASL id SUSE_11_XEN-130313.NASL
    description XEN has been updated to fix various bugs and security issues : - (XSA 36) To avoid an erratum in early hardware, the Xen AMD IOMMU code by default choose to use a single interrupt remapping table for the whole system. This sharing implied that any guest with a passed through PCI device that is bus mastering capable can inject interrupts into other guests, including domain 0. This has been disabled for AMD chipsets not capable of it. (CVE-2013-0153) - qemu: The e1000 had overflows under some conditions, potentially corrupting memory. (CVE-2012-6075) - (XSA 37) Hypervisor crash due to incorrect ASSERT (debug build only). (CVE-2013-0154) - (XSA-33) A VT-d interrupt remapping source validation flaw was fixed. Also the following bugs have been fixed :. (CVE-2012-5634) - xen hot plug attach/detach fails. (bnc#805094) - domain locking can prevent a live migration from completing. (bnc#802690) - no way to control live migrations. (bnc#797014) - fix logic error in stdiostream_progress - restore logging in xc_save - add options to control migration tunables - enabling xentrace crashes hypervisor.

    description The remote host is affected by the vulnerability described in GLSA-201309-24 (Xen: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details. Impact : Guest domains could possibly gain privileges, execute arbitrary code, or cause a Denial of Service on the host domain (Dom0). Additionally, guest domains could gain information about other virtual machines running on the same host or read arbitrary files on the host. Workaround : The CVEs listed below do not currently have fixes, but only apply to Xen setups which have “tmem” specified on the hypervisor command line. TMEM is not currently supported for use in production systems, and administrators using tmem should disable it. Relevant CVEs: * CVE-2012-2497 * CVE-2012-6030 * CVE-2012-6031 * CVE-2012-6032 * CVE-2012-6033 * CVE-2012-6034 * CVE-2012-6035 * CVE-2012-6036
