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 SuSE Local Security Checks NASL id OPENSUSE-2013-310.NASL description XEN was updated to fix various bugs and security issues : Security issues fixed : -

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.

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 last seen 2020-06-01 modified 2020-06-02 plugin id 63662 published 2013-01-23 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/63662 title RHEL 5 : kernel (RHSA-2013:0168)
