HGFS.sys in the VMware Tools package in VMware Workstation 5.x before 5.5.6 build 80404, VMware Player before 1.0.6 build 80404, VMware ACE before 1.0.5 build 79846, VMware Server before 1.0.5 build 80187, and VMware ESX 2.5.4 through 3.0.2 does not properly validate arguments in user-mode METHOD_NEITHER IOCTLs to the \.hgfs device, which allows guest OS users to modify arbitrary memory locations in guest kernel memory and gain privileges.

NWFILTER.SYS in Novell Client 4.91 SP 1 through SP 4 for Windows 2000, XP, and Server 2003 makes the .nwfilter device available for arbitrary user-mode input via METHOD_NEITHER IOCTLs, which allows local users to gain privileges by passing a kernel address as an argument and overwriting kernel memory locations.

Untrusted search path vulnerability in Adobe Reader and Acrobat 8.1.1 and earlier allows local users to execute arbitrary code via a malicious Security Provider library in the reader’s current working directory. NOTE: this issue might be subsumed by CVE-2008-0655.

STEngine.exe 3.5.0.20 in Novell ZENworks Endpoint Security Management (ESM) 3.5, and other ESM versions before 3.5.0.82, dynamically creates scripts in a world-writable directory when generating diagnostic reports, which allows local users to gain privileges, as demonstrated by creating a cmd.exe binary in the diagnostic report directory.

db2dasrrm in the DB2 Administration Server (DAS) in IBM DB2 Universal Database 9.5 before Fix Pack 1, 9.1 before Fix Pack 4a, and 8 before FixPak 16 allows local users to overwrite arbitrary files via a symlink attack on files used for initialization.
