CVE reference:	CVE-2003-0112

Description: A vulnerability has been identified in some versions of Windows, which can be exploited by malicious users on a vulnerable system to escalate their privileges. The vulnerability is caused by a boundary error in the kernel due to a flaw in the way error messages are passed to debuggers. A malicious user can exploit this by running a specially crafted program, which causes a buffer overflow by sending malformed debugger messages to the kernel. Successful exploitation allows a malicious user to execute arbitrary code on the vulnerable system with escalated privileges. Solution: Apply patch via Windows Update or manually. -- Windows NT 4.0 (with SP6a installed) -- All except Japanese NEC and Chinese - Hong Kong: http://microsoft.com/downloads/detail...-8BE5-91AE65619A1A&displaylang=en Japanese NEC: http://microsoft.com/downloads/detail...-9187-9B03E9AE825F&displaylang=ja Chinese - Hong Kong: http://microsoft.com/downloads/detail...82-557389FB4590&displaylang=zh-tw -- Windows NT 4.0, Terminal Server Edition (with SP6 installed) -- All: http://microsoft.com/downloads/detail...-9049-99A4CE52B5F8&displaylang=en -- Windows 2000 (any version with SP2/SP3 installed) -- All except Japanese NEC: http://microsoft.com/downloads/detail...-B565-5D7B3257A733&displaylang=en Japanese NEC: http://microsoft.com/downloads/detail...-98C1-4DDF6CF3893F&displaylang=ja -- Windows XP -- 32-bit Edition: http://microsoft.com/downloads/detail...-826A-4E0FEAB42323&displaylang=en 64-bit Edition: http://microsoft.com/downloads/detail...-9900-3DF363A51A3A&displaylang=en Original Advisory: http://microsoft.com/technet/security/bulletin/MS03-013.asp Other References: http://www.kb.cert.org/vuls/id/446338
