Microsoft : Security Vulnerabilities, CVEs, Published In May 2006

Buffer overflow in Microsoft Word in Office 2000 SP3, Office XP SP3, Office 2003 Sp1 and SP2, and Microsoft Works Suites through 2006, allows user-assisted attackers to execute arbitrary code via a malformed object pointer, as originally reported by ISC on 20060519 for a zero-day attack.

The RtlDosPathNameToNtPathName_U API function in NTDLL.DLL in Microsoft Windows 2000 SP4 and XP SP2 does not properly convert DOS style paths with trailing spaces into NT style paths, which allows context-dependent attackers to create files that cannot be accessed through the expected DOS path or prevent access to other similarly named files in the same directory, which prevents those files from being detected or disinfected by certain anti-virus and anti-spyware software.

Heap-based buffer overflow in Microsoft Infotech Storage System Library (itss.dll) allows user-assisted attackers to execute arbitrary code via a crafted CHM / ITS file that triggers the overflow while decompiling.

Unspecified vulnerability in Internet Explorer 6.0 on Microsoft Windows XP SP2 allows remote attackers to execute arbitrary code via "exceptional conditions" that trigger memory corruption, as demonstrated using an exception handler and nested object tags, a variant of CVE-2006-1992.

A component in Microsoft Outlook Express 6 allows remote attackers to bypass domain restrictions and obtain sensitive information via redirections with the mhtml: URI handler, as originally reported for Internet Explorer 6 and 7, aka "URL Redirect Cross Domain Information Disclosure Vulnerability."

Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0, 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote attackers to cause a denial of service (crash) via a BuildContextW request with a large (1) UuidString or (2) GuidIn of a certain length, which causes an out-of-range memory access, aka the MSDTC Denial of Service Vulnerability. NOTE: this is a variant of CVE-2005-2119.

Heap-based buffer overflow in the CRpcIoManagerServer::BuildContext function in msdtcprx.dll for Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0 and Windows 2000 SP2 and SP3 allows remote attackers to execute arbitrary code via a long fifth argument to the BuildContextW or BuildContext opcode, which triggers a bug in the NdrAllocate function, aka the MSDTC Invalid Memory Access Vulnerability.

Unspecified vulnerability in Microsoft Exchange allows remote attackers to execute arbitrary code via e-mail messages with crafted (1) vCal or (2) iCal Calendar properties.
