Patch Tuesday -April 14th

As I do now every month, I post up the Patch Impact Report for Microsoft's Patch Tuesday.

This month includes 8 patches, two rated Important, one moderate and the others are rated as Critical. These patches affect all operating systems from Windows 2000, XP through to VISTA and Windows 7 beta and system administrators should be aware that they will require all servers and desktops running these operating systems to be rebooted. Six of the eight patches explicitly state that a reboot is required, however the nature of the changes being made by the other two patches make it highly likely that these will also require a reboot although this is not explicitly stated in the documentation.

After loading the ChangeBase AOK application testing portfolio into a Patch Impact database, all eight patches were tested for application level issues and in addition, application dependencies. Only one update (MS09-014) raised a significant number of issues across a small number of applications across the ChangeBase Patch Testing Application portfolio.

Here is a sample report extract from one of the few applications in the AOK ChangeBase Application Test Portfolio that raised a dependency level issue with the MS09-014 Update.


Testing Summary

• MS09-009: Marginal Impact (both Package level and dependencies) detected across portfolio
• MS09-010: Marginal Impact (both Package level and dependencies) detected across portfolio
• MS09-011: Marginal Impact (both Package level and dependencies) detected across portfolio
• MS09-012: Marginal Impact (both Package level and dependencies) detected across portfolio
• MS09-013: Marginal Impact (both Package level and dependencies) detected across portfolio
• MS09-014: Moderate Impact (both Package level and dependencies) detected across portfolio
• MS09-015: Marginal Impact (both Package level and dependencies) detected across portfolio
• MS09-016: Marginal Impact (both Package level and dependencies) detected across portfolio

Security Update Detailed Summary

MS09-009	Vulnerabilities in Microsoft Office Excel Could Cause Remote Code Execution (968557)
Description	This security update resolves a privately reported and a publicly disclosed vulnerability. The vulnerabilities could allow remote code execution if the user opens a specially crafted Excel file. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Payload	Excel.exe
Impact	Remote Code Execution

MS09-010	Vulnerabilities in WordPad and Office Text Converters Could Allow Remote Code Execution (960477)
Description	This security update resolves two publicly disclosed vulnerabilities and two privately reported vulnerabilities in Microsoft WordPad and Microsoft Office text converters. The vulnerabilities could allow remote code execution if a specially crafted file is opened in WordPad or Microsoft Office Word. Do not open Microsoft Office, RTF, Write, or WordPerfect files from untrusted sources using affected versions of WordPad or Microsoft Office Word.
Payload	Html32.cnv, Msconv97.dll, Mswrd632.cnv, Mswrd832.cnv, Wpft532.cnv, Wpft632.cnv
Impact	Spoofing

MS09-011	Vulnerability in Microsoft DirectShow Could Allow Remote Code Execution (961373)
Description	This security update resolves a privately reported vulnerability in Microsoft DirectX. The vulnerability could allow remote code execution if user opened a specially crafted MJPEG file. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Payload	Quartz.dll
Impact	Remote Code Execution

MS09-012	Vulnerabilities in Windows Could Allow Elevation of Privilege (959454)
Description	This security update resolves four publicly disclosed vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker is allowed to log on to the system and then run a specially crafted application. The attacker must be able to run code on the local machine in order to exploit this vulnerability. An attacker who successfully exploited any of these vulnerabilities could take complete control over the affected system.
Payload	Dtcsetup.exe, Msdtclog.dll, Msdtcprx.dll, Msdtctm.dll, Msdtcui.dll, Mtxclu.dll, Mtxoci.dll, Sp3res.dll, Xolehlp.dll

MS09-013	Vulnerabilities in Windows HTTP Services Could Allow Remote Code Execution (960803)
Description	This security update resolves one publicly disclosed vulnerability and two privately reported vulnerabilities in Microsoft Windows HTTP Services (WinHTTP). The most severe vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
