    description An update for qemu-kvm is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm packages provide the user-space component for running virtual machines using KVM. Security Fix(es) : * An integer overflow flaw and an out-of-bounds read flaw were found in the way QEMU's VGA emulator set certain VGA registers while in VBE mode. A privileged guest user could use this flaw to crash the QEMU process instance. (CVE-2016-3712) * An infinite loop flaw was found in the way QEMU's e1000 NIC emulation implementation processed data using transmit or receive descriptors under certain conditions. A privileged user inside a guest could use this flaw to crash the QEMU instance. (CVE-2016-1981) Red Hat would like to thank Zuozhi Fzz (Alibaba Inc.) for reporting CVE-2016-3712. Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.

    description The Xen Project reports : Qemu VGA module allows banked access to video memory using the window at 0xa00000 and it supports different access modes with different address calculations. Qemu VGA module allows guest to edit certain registers in 'vbe' and 'vga' modes. A privileged guest user could use CVE-2016-3710 to exceed the bank address window and write beyond the said memory area, potentially leading to arbitrary code execution with privileges of the Qemu process. If the system is not using stubdomains, this will be in domain 0. A privileged guest user could use CVE-2016-3712 to cause potential integer overflow or OOB read access issues in Qemu, resulting in a DoS of the guest itself. More dangerous effect, such as data leakage or code execution, are not known but cannot be ruled out.

    description Multiple vulnerabilities have been discovered in the Xen hypervisor. The Common Vulnerabilities and Exposures project identifies the following problems : CVE-2014-3672 (XSA-180) Andrew Sorensen discovered that a HVM domain can exhaust the hosts disk space by filling up the log file. CVE-2016-3158, CVE-2016-3159 (XSA-172) Jan Beulich from SUSE discovered that Xen does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors. A malicious domain can take advantage of this flaw to obtain address space usage and timing information, about another domain, at a fairly low rate. CVE-2016-3710 (XSA-179) Wei Xiao and Qinghao Tang of 360.cn Inc discovered an out-of-bounds read and write flaw in the QEMU VGA module. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. CVE-2016-3712 (XSA-179) Zuozhi Fzz of Alibaba Inc discovered potential integer overflow or out-of-bounds read access issues in the QEMU VGA module. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash). CVE-2016-3960 (XSA-173) Ling Liu and Yihan Lian of the Cloud Security Team, Qihoo 360 discovered an integer overflow in the x86 shadow pagetable code. A HVM guest using shadow pagetables can cause the host to crash. A PV guest using shadow pagetables (i.e. being migrated) with PV superpages enabled (which is not the default) can crash the host, or corrupt hypervisor memory, potentially leading to privilege escalation. CVE-2016-4480 (XSA-176) Jan Beulich discovered that incorrect page table handling could result in privilege escalation inside a Xen guest instance. CVE-2016-6258 (XSA-182) Jérémie Boutoille discovered that incorrect pagetable handling in PV instances could result in guest to host privilege escalation. Additionally this Xen Security Advisory without a CVE was fixed : XSA-166 Konrad Rzeszutek Wilk and Jan Beulich discovered that ioreq handling is possibly susceptible to a multiple read issue. For Debian 7 'Wheezy', these problems have been fixed in version 4.1.6.lts1-1. We recommend that you upgrade your xen packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    NASL id CITRIX_XENSERVER_CTX212736.NASL
    description The version of Citrix XenServer running on the remote host is affected by multiple vulnerabilities in the bundled versions of OpenSSL and QEMU : - Multiple flaws exist in the bundled version of OpenSSL in the aesni_cbc_hmac_sha1_cipher() and aesni_cbc_hmac_sha256_cipher() functions that are triggered when the connection uses an AES-CBC cipher and AES-NI is supported by the server. A man-in-the-middle attacker can exploit these issues to conduct a padding oracle attack, resulting in the ability to decrypt the network traffic. (CVE-2016-2107) - A remote code execution vulnerability exists in the bundled version of OpenSSL in the ASN.1 encoder component due to an underflow condition that occurs when attempting to encode the value zero represented as a negative integer. An unauthenticated, remote attacker can exploit this to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-2108) - An out-of-bounds write error exists in the bundled version of QEMU in the vga_update_memory_access() function that is triggered when access nodes are changed after the register bank has been set. An attacker on the guest can exploit this to execute arbitrary code with the privileges of the host's QEMU process. (CVE-2016-3710) - An integer overflow condition exists in the bundled version of QEMU in the vbe_update_vgaregs() function that is triggered when setting certain VGA registers while in VBE mode. An attacker on the guest can exploit this to crash the host's QEMU process. (CVE-2016-3712)

    description An update for qemu-kvm is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM. Security Fix(es) : * An integer overflow flaw and an out-of-bounds read flaw were found in the way QEMU's VGA emulator set certain VGA registers while in VBE mode. A privileged guest user could use this flaw to crash the QEMU process instance. (CVE-2016-3712) Red Hat would like to thank Zuozhi Fzz (Alibaba Inc.) for reporting this issue. Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.

    title SUSE SLES11 Security Update : kvm (SUSE-SU-2016:1698-1)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2017-0621.NASL
    description An update for qemu-kvm is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM. Security Fix(es) : * An integer overflow flaw and an out-of-bounds read flaw were found in the way QEMU's VGA emulator set certain VGA registers while in VBE mode. A privileged guest user could use this flaw to crash the QEMU process instance. (CVE-2016-3712) Red Hat would like to thank Zuozhi Fzz (Alibaba Inc.) for reporting this issue. Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.
