Vulnerability from variot
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. QEMU is prone to a memory-corruption vulnerability because it fails to perform adequate boundary-checks on user-supplied data. An attacker can exploit this issue to execute arbitrary code on the host with the privileges of the hosting QEMU process. Failed exploit attempts may result in a denial-of-service condition. The Linux kernel is the kernel used by the open source operating system Linux released by the American Linux Foundation. The NFSv4 implementation is one of the distributed file system protocols. QEMU (also known as Quick Emulator) is a set of analog processor software developed by French programmer Fabrice Bellard. The software has the characteristics of fast speed and cross-platform. There is a security vulnerability in the 'pit_ioport_read' function in the i8254.c file of Linux kernel 2.6.32 and earlier versions and QEMU 2.3.0 and earlier versions. The vulnerability is due to the fact that the program does not distinguish between read length and write length. Relevant releases/architectures:

- Summary:
Updated qemu-kvm packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security 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.
- Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64
- Description:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM.
A heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. (CVE-2015-5154)
An out-of-bounds memory access flaw, leading to memory corruption or possibly an information leak, was found in QEMU's pit_ioport_read() function. (CVE-2015-3214)
Red Hat would like to thank Matt Tait of Google's Project Zero security team for reporting the CVE-2015-3214 issue. The CVE-2015-5154 issue was discovered by Kevin Wolf of Red Hat.
This update also fixes the following bug:
- Due to an incorrect implementation of portable memory barriers, the QEMU emulator in some cases terminated unexpectedly when a virtual disk was under heavy I/O load. This update fixes the implementation in order to achieve correct synchronization between QEMU's threads. As a result, the described crash no longer occurs. (BZ#1233643)
All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.
- Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.

"data": "The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. QEMU is prone to a memory-corruption vulnerability because it fails to perform adequate boundary-checks on user-supplied data. \nAn attacker can exploit this issue to execute arbitrary code on the host with the privileges of the hosting QEMU process. Failed exploit attempts may result in a denial-of-service condition. The Linux kernel is the kernel used by the open source operating system Linux released by the American Linux Foundation. The NFSv4 implementation is one of the distributed file system protocols. QEMU (also known as Quick Emulator) is a set of analog processor software developed by French programmer Fabrice Bellard. The software has the characteristics of fast speed and cross-platform. There is a security vulnerability in the \u0027pit_ioport_read\u0027 function in the i8254.c file of Linux kernel 2.6.32 and earlier versions and QEMU 2.3.0 and earlier versions. The vulnerability is due to the fact that the program does not distinguish between read length and write length. Relevant releases/architectures:\n\nRHEV-H and VDSM for 7 Hosts - x86_64\n\n3. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: qemu-kvm security and bug fix update\nAdvisory ID: RHSA-2015:1507-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://rhn.redhat.com/errata/RHSA-2015-1507.html\nIssue date: 2015-07-27\nCVE Names: CVE-2015-3214 CVE-2015-5154 \n=====================================================================\n\n1. Summary:\n\nUpdated qemu-kvm packages that fix two security issues and one bug are now\navailable for Red Hat Enterprise Linux 7. \n\nRed Hat Product Security has rated this update as having Important security\nimpact. Common Vulnerability Scoring System (CVSS) base scores, which give\ndetailed severity ratings, are available for each vulnerability from the\nCVE links in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Client (v. 7) - x86_64\nRed Hat Enterprise Linux Client Optional (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64\nRed Hat Enterprise Linux Server (v. 7) - ppc64, x86_64\nRed Hat Enterprise Linux Server Optional (v. 7) - ppc64, x86_64\nRed Hat Enterprise Linux Workstation (v. 7) - x86_64\nRed Hat Enterprise Linux Workstation Optional (v. 7) - x86_64\n\n3. Description:\n\nKVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. The qemu-kvm package provides the\nuser-space component for running virtual machines using KVM. \n\nA heap buffer overflow flaw was found in the way QEMU\u0027s IDE subsystem\nhandled I/O buffer access while processing certain ATAPI commands. \n(CVE-2015-5154)\n\nAn out-of-bounds memory access flaw, leading to memory corruption or\npossibly an information leak, was found in QEMU\u0027s pit_ioport_read()\nfunction. (CVE-2015-3214)\n\nRed Hat would like to thank Matt Tait of Google\u0027s Project Zero security\nteam for reporting the CVE-2015-3214 issue. The CVE-2015-5154 issue was\ndiscovered by Kevin Wolf of Red Hat. \n\nThis update also fixes the following bug:\n\n* Due to an incorrect implementation of portable memory barriers, the QEMU\nemulator in some cases terminated unexpectedly when a virtual disk was\nunder heavy I/O load. This update fixes the implementation in order to\nachieve correct synchronization between QEMU\u0027s threads. As a result, the\ndescribed crash no longer occurs. (BZ#1233643)\n\nAll qemu-kvm users are advised to upgrade to these updated packages, which\ncontain backported patches to correct these issues. After installing this\nupdate, shut down all running virtual machines. Once all virtual machines\nhave shut down, start them again for this update to take effect. \n\n4. Solution:\n\nBefore applying this update, make sure all previously released errata\nrelevant to your system have been applied. \n\nFor details on how to apply this update, refer to:\n\nhttps://access.redhat.com/articles/11258\n\n5.

In the default installation, when QEMU is\nused with libvirt, attackers would be isolated by the libvirt AppArmor\nprofile. In the default installation, when QEMU is used with\nlibvirt, attackers would be isolated by the libvirt AppArmor profile. \n(CVE-2015-5154)\n\nZhu Donghai discovered that QEMU incorrectly handled the SCSI driver. In the default installation, when QEMU is used with libvirt,\nattackers would be isolated by the libvirt AppArmor profile. This issue\nonly affected Ubuntu 15.04. (CVE-2015-5158)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 15.04:\n qemu-system 1:2.2+dfsg-5expubuntu9.3\n qemu-system-aarch64 1:2.2+dfsg-5expubuntu9.3\n qemu-system-arm 1:2.2+dfsg-5expubuntu9.3\n qemu-system-mips 1:2.2+dfsg-5expubuntu9.3\n qemu-system-misc 1:2.2+dfsg-5expubuntu9.3\n qemu-system-ppc 1:2.2+dfsg-5expubuntu9.3\n qemu-system-sparc 1:2.2+dfsg-5expubuntu9.3\n qemu-system-x86 1:2.2+dfsg-5expubuntu9.3\n\nUbuntu 14.04 LTS:\n qemu-system 2.0.0+dfsg-2ubuntu1.15\n qemu-system-aarch64 2.0.0+dfsg-2ubuntu1.15\n qemu-system-arm 2.0.0+dfsg-2ubuntu1.15\n qemu-system-mips 2.0.0+dfsg-2ubuntu1.15\n qemu-system-misc 2.0.0+dfsg-2ubuntu1.15\n qemu-system-ppc 2.0.0+dfsg-2ubuntu1.15\n qemu-system-sparc 2.0.0+dfsg-2ubuntu1.15\n qemu-system-x86 2.0.0+dfsg-2ubuntu1.15\n\nAfter a standard system update you need to restart all QEMU virtual\nmachines to make all the necessary changes. \n\nCVE-2015-5165\n\n Donghai Zhu discovered that the QEMU model of the RTL8139 network\n card did not sufficiently validate inputs in the C+ mode offload\n emulation, allowing a malicious guest to read uninitialized memory\n from the QEMU process\u0027s heap. \n\nCVE-2015-5225\n\n Mr Qinghao Tang from QIHU 360 Inc. \n\nFor the oldstable distribution (wheezy), these problems have been fixed\nin version 1.1.2+dfsg-6a+deb7u9. The oldstable distribution is only\naffected by CVE-2015-5165 and CVE-2015-5745. \n\nFor the stable distribution (jessie), these problems have been fixed in\nversion 1:2.1+dfsg-12+deb8u2. \n\nFor the unstable distribution (sid), these problems have been fixed in\nversion 1:2.4+dfsg-1a. \n\nWe recommend that you upgrade your qemu packages. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory GLSA 201510-02\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: Normal\n Title: QEMU: Arbitrary code execution\n Date: October 31, 2015\n Bugs: #551752, #555680, #556050, #556052\n ID: 201510-02\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n========\n\nA heap-based buffer overflow in QEMU could result in execution of\narbitrary code. \n\nAffected packages\n=================\n\n -------------------------------------------------------------------\n Package / Vulnerable / Unaffected\n -------------------------------------------------------------------\n 1 app-emulation/qemu \u003c 2.3.0-r4 \u003e= 2.3.0-r4\n\nDescription\n===========\n\nHeap-based buffer overflow has been found in QEMU\u0027s PCNET controller. \n\nWorkaround\n==========\n\nThere is no known workaround at this time. \n\nResolution\n==========\n\nAll QEMU users should upgrade to the latest version:\n\n # emerge --sync\n # emerge --ask --oneshot --verbose \"\u003e=app-emulation/qemu-2.3.0-r4\"\n\nReferences\n==========\n\n[ 1 ] CVE-2015-3209\n http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-3209\n[ 2 ] CVE-2015-3214\n http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-3214\n[ 3 ] CVE-2015-5154\n http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-5154\n[ 4 ] CVE-2015-5158\n http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-5158\n\nAvailability\n============\n\nThis GLSA and any updates to it are available for viewing at\nthe Gentoo Security Website:\n\n https://security.gentoo.org/glsa/201510-02\n\nConcerns?\n=========\n\nSecurity is a primary focus of Gentoo Linux and ensuring the\nconfidentiality and security of our users\u0027 machines is of utmost\nimportance to us.
