NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2012-1540.NASL description Updated kernel packages that fix multiple security issues, two bugs, and add two enhancements are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important 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. These packages contain the Linux kernel. Security fixes : * A race condition in the way asynchronous I/O and fallocate() interacted when using ext4 could allow a local, unprivileged user to obtain random data from a deleted file. (CVE-2012-4508, Important) * A flaw in the way the Xen hypervisor implementation range checked guest provided addresses in the XENMEM_exchange hypercall could allow a malicious, para-virtualized guest administrator to crash the hypervisor or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. (CVE-2012-5513, Important) * A flaw in the Reliable Datagram Sockets (RDS) protocol implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2012-2372, Moderate) * A race condition in the way access to inet->opt ip_options was synchronized in the Linux kernel last seen 2020-06-01 modified 2020-06-02 plugin id 63171 published 2012-12-07 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/63171 title CentOS 5 : kernel (CESA-2012:1540) NASL family Fedora Local Security Checks NASL id FEDORA_2012-18242.NASL description A guest can block a cpu by setting a bad VCPU deadline [XSA 20, CVE-2012-4535] (#876198) HVM guest can use invalid pirq values to crash xen [XSA 21, CVE-2012-4536] (#876200) HVM guest can exhaust p2m table crashing xen [XSA 22, CVE-2012-4537] (#876203) PAE HVM guest can crash hypervisor [XSA-23, CVE-2012-4538] (#876205) 32-bit PV guest on 64-bit hypervisor can cause an hypervisor infinite loop [XSA-24, CVE-2012-4539] (#876207) Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.

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 last seen 2020-06-05 modified 2015-05-20 plugin id 83616 published 2015-05-20 reporter This script is Copyright (C) 2015-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/83616 title SUSE SLES11 Security Update : Xen (SUSE-SU-2014:0446-1) NASL family SuSE Local Security Checks NASL id SUSE_SU-2014-0470-1.NASL 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 last seen 2020-06-05 modified 2015-05-20 plugin id 83617 published 2015-05-20 reporter This script is Copyright (C) 2015-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/83617 title SUSE SLES10 Security Update : Xen (SUSE-SU-2014:0470-1) NASL family OracleVM Local Security Checks NASL id ORACLEVM_OVMSA-2015-0068.NASL description The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2015-0068 for details. last seen 2020-06-01 modified 2020-06-02 plugin id 84140 published 2015-06-12 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/84140 title OracleVM 3.2 : xen (OVMSA-2015-0068) (POODLE) (Venom) NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201309-24.NASL description The remote host is affected by the vulnerability described in GLSA-201309-24 (Xen: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in Xen.

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 Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2012-1540-1.NASL description From Red Hat Security Advisory 2012:1540 : Updated kernel packages that fix multiple security issues, two bugs, and add two enhancements are now available for Red Hat Enterprise Linux 5.

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.
