The Virtual Machine Communication Interface (VMCI) implementation in vmci.sys in VMware Workstation 8.x before 8.0.5 and 9.x before 9.0.1 on Windows, VMware Fusion 4.1 before 4.1.4 and 5.0 before 5.0.2, VMware View 4.x before 4.6.2 and 5.x before 5.1.2 on Windows, VMware ESXi 4.0 through 5.1, and VMware ESX 4.0 and 4.1 does not properly restrict memory allocation by control code, which allows local users to gain privileges via unspecified vectors.

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by a privilege escalation vulnerability in the Virtual Machine Communication Interface (VMCI) due to improper handling of control code in vmci.sys. A local attacker can exploit this to change memory allocation, resulting in an escalation of privileges on Windows-based guest operating systems.

Note that systems with VMCI disabled are still affected by the vulnerability.

The remote VMware ESXi 5.1 host is affected by the following security vulnerabilities :

  - An input validation error exists in the function     'png_set_text_2' in the libpng library that could     allow memory corruption and arbitrary code execution.
    (CVE-2011-3048)

  - A privilege escalation vulnerability exists in the     Virtual Machine Communication Interface (VMCI). A local     attacker can exploit this, via control code, to change     allocated memory, resulting in the escalation of     privileges. (CVE-2013-1406)

  - An error exists related to Network File Copy (NFC)     handling that could allow denial of service attacks or     arbitrary code execution. (CVE-2013-1659)

The remote VMware ESXi 5.0 host is affected by Multiple Vulnerabilities :

  - An integer overflow condition exists in the
    __tzfile_read() function in the glibc library. An     unauthenticated, remote attacker can exploit this, via     a crafted timezone (TZ) file, to cause a denial of     service or the execution of arbitrary code.
    (CVE-2009-5029)

  - ldd in the glibc library is affected by a privilege     escalation vulnerability due to the omission of certain     LD_TRACE_LOADED_OBJECTS checks in a crafted executable     file. Note that this vulnerability is disputed by the     library vendor. (CVE-2009-5064)

  - A remote code execution vulnerability exists in the     glibc library due to an integer signedness error in the     elf_get_dynamic_info() function when the '--verify'     option is used. A remote attacker can exploit this by     using a crafted ELF program with a negative value for a     certain d_tag structure member in the ELF header.
    (CVE-2010-0830)

  - A flaw exists in OpenSSL due to a failure to properly     prevent modification of the ciphersuite in the session     cache when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is     enabled. A remote attacker can exploit this to force a     downgrade to an unintended cipher by intercepting the     network traffic to discover a session identifier.
    (CVE-2010-4180)

  - A flaw exists in OpenSSL due to a failure to properly     validate the public parameters in the J-PAKE protocol     when J-PAKE is enabled. A remote attacker can exploit     this, by sending crafted values in each round of the     protocol, to bypass the need for knowledge of the shared     secret. (CVE-2010-4252)

  - A out-of-bounds memory error exists in OpenSSL that     allows a remote attacker to cause a denial of service or     possibly obtain sensitive information by using a     malformed ClientHello handshake message. This is also     known as the 'OCSP stapling vulnerability'.
    (CVE-2011-0014)

  - A flaw exists in the addmntent() function in the glibc     library due to a failure to report the error status for     failed attempts to write to the /etc/mtab file. A local     attacker can exploit this to corrupt the file by using     writes from a process with a small RLIMIT_FSIZE value.
    (CVE-2011-1089)

  - A flaw exists in the png_set_text_2() function in the     file pngset.c in the libpng library due to a failure to     properly allocate memory. An unauthenticated, remote     attacker can exploit this, via a crafted text chunk in a     PNG image file, to trigger a heap-based buffer overflow,     resulting in denial of service or the execution of     arbitrary code. (CVE-2011-3048)

  - A flaw exists in the DTLS implementation in OpenSSL due     to performing a MAC check only if certain padding is     valid. A remote attacker can exploit this, via a padding     oracle attack, to recover the plaintext. (CVE-2011-4108)

  - A double-free error exists in OpenSSL when the     X509_V_FLAG_POLICY_CHECK is enabled. A remote attacker     can exploit this by triggering a policy check failure,     resulting in an unspecified impact. (CVE-2011-4109)

  - A flaw exists in OpenSSL in the SSL 3.0 implementation     due to improper initialization of data structures used     for block cipher padding. A remote attacker can exploit     this, by decrypting the padding data sent by an SSL     peer, to obtain sensitive information. (CVE-2011-4576)

  - A denial of service vulnerability exists in OpenSSL when     RFC 3779 support is enabled. A remote attacker can     exploit this to cause an assertion failure, by using an     X.509 certificate containing certificate extension data     associated with IP address blocks or Autonomous System     (AS) identifiers. (CVE-2011-4577)

  - A denial of service vulnerability exists in the RPC     implementation in the glibc library due to a flaw in the     svc_run() function. A remote attacker can exploit this,     via large number of RPC connections, to exhaust CPU     resources. (CVE-2011-4609)

  - A denial of service vulnerability exists in the Server     Gated Cryptography (SGC) implementation in OpenSSL due     to a failure to properly handle handshake restarts. A     remote attacker can exploit this, via unspecified     vectors, to exhaust CPU resources. (CVE-2011-4619)

  - A denial of service vulnerability exists in OpenSSL due     to improper support of DTLS applications. A remote     attacker can exploit this, via unspecified vectors     related to an out-of-bounds read error. Note that this     vulnerability exists because of an incorrect fix for     CVE-2011-4108. (CVE-2012-0050)

  - A security bypass vulnerability exists in the glibc     library due to an integer overflow condition in the     vfprintf() function in file stdio-common/vfprintf.c. An     attacker can exploit this, by using a large number of     arguments, to bypass the FORTIFY_SOURCE protection     mechanism, allowing format string attacks or writing to     arbitrary memory. (CVE-2012-0864)

  - A denial of service vulnerability exists in the glibc     library in the vfprintf() function in file     stdio-common/vfprintf.c due to a failure to properly     calculate a buffer length. An attacker can exploit this,     via a format string that uses positional parameters and     many format specifiers, to bypass the FORTIFY_SOURCE     format-string protection mechanism, thus causing stack     corruption and a crash. (CVE-2012-3404)

  - A denial of service vulnerability exists in the glibc     library in the vfprintf() function in file     stdio-common/vfprintf.c due to a failure to properly     calculate a buffer length. An attacker can exploit this,     via a format string with a large number of format     specifiers, to bypass the FORTIFY_SOURCE format-string     protection mechanism, thus triggering desynchronization     within the buffer size handling, resulting in a     segmentation fault and crash. (CVE-2012-3405)

  - A flaw exists in the glibc library in the vfprintf()     function in file stdio-common/vfprintf.c due to a     failure to properly restrict the use of the alloca()     function when allocating the SPECS array. An attacker     can exploit this, via a crafted format string using     positional parameters and a large number of format     specifiers, to bypass the FORTIFY_SOURCE format-string     protection mechanism, thus triggering a denial of     service or the possible execution of arbitrary code.
    (CVE-2012-3406)

  - A flaw exists in the glibc library due to multiple     integer overflow conditions in the strtod(), strtof(),     strtold(), strtod_l(), and other unspecified related     functions. A local attacker can exploit these to trigger     a stack-based buffer overflow, resulting in an     application crash or the possible execution of arbitrary     code. (CVE-2012-3480)

  - A privilege escalation vulnerability exists in the     Virtual Machine Communication Interface (VMCI) due to a     failure by control code to properly restrict memory     allocation. A local attacker can exploit this, via     unspecified vectors, to gain privileges. (CVE-2013-1406)

  - An error exists in the implementation of the Network     File Copy (NFC) protocol. A man-in-the-middle attacker     can exploit this, by modifying the client-server data     stream, to cause a denial of service or the execution     of arbitrary code. (CVE-2013-1659)

The version of VMware Workstation installed on the remote host is a version prior to 8.0.5 / 9.0.1.  It is, therefore, reportedly affected by a privilege escalation vulnerability in the Virtual Machine Communication Interface (VMCI) in the 'VMCI.sys' driver. 

By exploiting this issue, a local attacker could elevate their privileges on Windows-based hosts or Windows-based Guest Operating Systems. 

Note that systems that have VMCI disabled are also affected by this issue.

The version of VMware View installed on the remote host is a version prior to 4.6.2 / 5.1.2.  It is, therefore, reportedly affected by a privilege escalation vulnerability in the Virtual Machine Communication Interface (VMCI) in the 'VMCI.sys' driver. 

By exploiting this issue, a local attacker could elevate their privileges on Windows-based hosts or Windows-based Guest Operating Systems. 

Note that systems that have VMCI disabled are also affected by this issue.

The version of VMware Fusion installed on the Mac OS X host is a version prior to 4.1.4 / 5.0.2.  It is, therefore, reportedly affected by a privilege escalation vulnerability in the Virtual Machine Communication Interface (VMCI). 

By exploiting this issue, a local attacker could elevate their privileges on Windows-based hosts or Windows-based Guest Operating Systems. 

Note that systems that have VMCI disabled are also affected by this issue.

a. VMware VMCI privilege escalation

   VMware ESX, Workstation, Fusion, and View contain a    vulnerability in the handling of control code in vmci.sys.
   A local malicious user may exploit this vulnerability to    manipulate the memory allocation through the Virtual    Machine Communication Interface (VMCI) code. This could    result in a privilege escalation on Windows-based hosts and    on Windows-based Guest Operating Systems.

   The vulnerability does not allow for privilege escalation    from the Guest Operating System to the host (and vice versa).
   This means that host memory can not be manipulated from the    Guest Operating System (and vice versa).

   Systems that have VMCI disabled are also affected by this issue.

   VMware would like to thank Derek Soeder of Cylance, Inc. and    Kostya Kortchinsky of Microsoft for independently reporting this    issue to us. 

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2013-1406 to this issue.
