VMware Workstation 6.5.x before 6.5.3 build 185404, VMware Player 2.5.x before 2.5.3 build 185404, VMware ACE 2.5.x before 2.5.3 build 185404, VMware Server 1.x before 1.0.10 build 203137 and 2.x before 2.0.2 build 203138, VMware Fusion 2.x before 2.0.6 build 196839, VMware ESXi 3.5 and 4.0, and VMware ESX 2.5.5, 3.0.3, 3.5, and 4.0, when Virtual-8086 mode is used, do not properly set the exception code upon a page fault (aka #PF) exception, which allows guest OS users to gain privileges on the guest OS by specifying a crafted value for the cs register.

VMware Authentication Daemon 1.0 in vmware-authd.exe in the VMware Authorization Service in VMware Workstation 7.0 before 7.0.1 build 227600 and 6.5.x before 6.5.4 build 246459, VMware Player 3.0 before 3.0.1 build 227600 and 2.5.x before 2.5.4 build 246459, VMware ACE 2.6 before 2.6.1 build 227600 and 2.5.x before 2.5.4 build 246459, and VMware Server 2.x allows remote attackers to cause a denial of service (process crash) via a \x25\xFF sequence in the USER and PASS commands, related to a "format string DoS" issue. NOTE: some of these details are obtained from third party information.

The VMnc media codec in vmnc.dll in VMware Movie Decoder before 6.5.3 build 185404, VMware Workstation 6.5.x before 6.5.3 build 185404, VMware Player 2.5.x before 2.5.3 build 185404, and VMware ACE 2.5.x before 2.5.3 build 185404 on Windows does not properly handle certain small heights in video content, which might allow remote attackers to execute arbitrary code via a crafted AVI file that triggers heap memory corruption.

Heap-based buffer overflow in the VMnc media codec in vmnc.dll in VMware Movie Decoder before 6.5.3 build 185404, VMware Workstation 6.5.x before 6.5.3 build 185404, VMware Player 2.5.x before 2.5.3 build 185404, and VMware ACE 2.5.x before 2.5.3 build 185404 on Windows might allow remote attackers to execute arbitrary code via a video file with crafted dimensions (aka framebuffer parameters).

vmware-config.pl in VMware for Linux, ESX Server 2.x, and Infrastructure 3 does not check the return code from a Perl chmod function call, which might cause an SSL key file to be created with an unsafe umask that allows local users to read or modify the SSL key.

Heap-based buffer overflow in the NAT networking components vmnat.exe and vmnet-natd in VMWare Workstation 5.5, GSX Server 3.2, ACE 1.0.1, and Player 1.0 allows remote authenticated attackers, including guests, to execute arbitrary code via crafted (1) EPRT and (2) PORT FTP commands.
