The Print Spooler service is an executable file that is installed as a service. The spooler is loaded when the operating system starts, and it continues to run until the operating system is shut down. The Print Spooler service manages the printing process, which includes such tasks as retrieving the location of the correct printer driver, loading that driver, spooling high-level function calls into a print job and scheduling print jobs.
An elevation of privilege vulnerability exists in the way that Microsoft Windows Print Spooler handles memory when a printer is deleted. This vulnerability is caused when the Windows Print Spooler does not properly free memory when a printer connection is deleted. (CVE-2013-1339)

Microsoft Office Remote Code Execution (MS13-051)
- Severity
- Critical 4
- Qualys ID
- 110212
- Vendor Reference
- MS13-051
- CVE Reference
- CVE-2013-1331
- CVSS Scores
- Base 9.3 / Temporal 8.1
- Description
-
This security update resolves one privately reported vulnerability in Microsoft Office.
The security update addresses the vulnerability by correcting the way that Microsoft Office parses specially crafted Office files.
This security update is rated Important for supported editions of Microsoft Office 2003 and Microsoft Office for Mac 2011.
- Consequence
- If this vulnerability is successfully exploited, attackers can run arbitrary code in the context of the current user.
- Solution
-
Workaround:
Do not open Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file. For Microsoft Office for Mac 2011, disassociate binary Office file formats from Office for Mac in OS X's LaunchServices database Note This workaround prevents Office files from being automatically opened through file format association. However, users are still vulnerable if they choose to manually open malicious Office files from within an Office application.Patches:
