Description

The version of VMware Fusion installed on the Mac OS X host is earlier than 3.1.3. As such, it is reportedly affected by the following three security vulnerabilities :

  • An attacker with access to a Guest operating system can determine if a path exists in the Host filesystem and whether it's a file or a directory regardless of permissions. (CVE-2011-2146)

  • A race condition in mount.vmhgfs may allow an attacker with access to a Guest to mount on arbitrary directories in the Guest filesystem and escalate their privileges if they can control the contents of the mounted directory. (CVE-2011-1787)

  • A procedural error allows an attacker with access to a Solaris or FreeBSD Guest operating system to gain write access to an arbitrary file in the Guest filesystem. (CVE-2011-2145)

  • A buffer overflow in the way UDF file systems are handled could allow for code execution if a specially crafted ISO image is used. (CVE-2011-3868)

Note that the first three vulnerabilities only affect non-Windows guest operating systems.
