Summary

Race condition in mount.vmhgfs in the VMware Host Guest File System (HGFS) in VMware Workstation 7.1.x before 7.1.4, VMware Player 3.1.x before 3.1.4, VMware Fusion 3.1.x before 3.1.3, VMware ESXi 3.5 through 4.1, and VMware ESX 3.0.3 through 4.1 allows guest OS users to gain privileges on the guest OS by mounting a filesystem on top of an arbitrary directory.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging Race Conditions
    This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
  • Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
    This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

    descriptionThe remote VMware ESX / ESXi host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in the Linux Kernel in the do_anonymous_page() function due to improper separation of the stack and the heap. An attacker can exploit this to execute arbitrary code. (CVE-2010-2240) - A packet filter bypass exists in the Linux Kernel e1000 driver due to processing trailing payload data as a complete frame. A remote attacker can exploit this to bypass packet filters via a large packet with a crafted payload. (CVE-2009-4536) - A use-after-free error exists in the Linux Kernel when IPV6_RECVPKTINFO is set on a listening socket. A remote attacker can exploit this, via a SYN packet while the socket is in a listening (TCP_LISTEN) state, to cause a kernel panic, resulting in a denial of service condition. (CVE-2010-1188) - An array index error exists in the Linux Kernel in the gdth_read_event() function. A local attacker can exploit this, via a negative event index in an IOCTL request, to cause a denial of service condition. (CVE-2009-3080) - A race condition exists in the VMware Host Guest File System (HGFS) that allows guest operating system users to gain privileges by mounting a filesystem on top of an arbitrary directory. (CVE-2011-1787) - A flaw exists in the VMware Host Guest File System (HGFS) that allows a Solaris or FreeBSD guest operating system user to modify arbitrary guest operating system files. (CVE-2011-2145) - A flaw exists in the VMware Host Guest File System (HGFS) that allows guest operating system users to disclose host operating system files and directories. (CVE-2011-2146) - A flaw exists in the bundled Tom Sawyer GET Extension Factory that allows a remote attacker to cause a denial of service condition or the execution of arbitrary code via a crafted HTML document.

    descriptiona. VMware vmkernel third-party e1000(e) Driver Packet Filter Bypass There is an issue in the e1000(e) Linux driver for Intel PRO/1000 adapters that allows a remote attacker to bypass packet filters. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4536 to this issue. b. ESX third-party update for Service Console kernel This update for the console OS kernel package resolves four security issues. 1) IPv4 Remote Denial of Service An remote attacker can achieve a denial of service via an issue in the kernel IPv4 code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1188 to this issue. 2) SCSI Driver Denial of Service / Possible Privilege Escalation A local attacker can achieve a denial of service and possibly a privilege escalation via a vulnerability in the Linux SCSI drivers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3080 to this issue. 3) Kernel Memory Management Arbitrary Code Execution A context-dependent attacker can execute arbitrary code via a vulnerability in a kernel memory handling function. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2240 to this issue. 4) e1000 Driver Packet Filter Bypass There is an issue in the Service Console e1000 Linux driver for Intel PRO/1000 adapters that allows a remote attacker to bypass packet filters. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-4536 to this issue. c. Multiple vulnerabilities in mount.vmhgfs This patch provides a fix for the following three security issues in the VMware Host Guest File System (HGFS). None of these issues affect Windows based Guest Operating Systems. 1) Mount.vmhgfs Information Disclosure Information disclosure via a vulnerability that allows an attacker with access to the Guest to determine if a path exists in the Host filesystem and whether it is a file or directory regardless of permissions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-2146 to this issue. 2) Mount.vmhgfs Race Condition Privilege escalation via a race condition that allows an attacker with access to the guest to mount on arbitrary directories in the Guest filesystem and achieve privilege escalation if they can control the contents of the mounted directory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-1787 to this issue. 3) Mount.vmhgfs Privilege Escalation Privilege escalation via a procedural error that allows an attacker with access to the guest operating system to gain write access to an arbitrary file in the Guest filesystem. This issue only affects Solaris and FreeBSD Guest Operating Systems. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-2145 to this issue. VMware would like to thank Dan Rosenberg for reporting these issues. d.
