  Severity

  Urgent 5

  Qualys ID

  90851

  Vendor Reference

  MS13-001

  CVE Reference

  CVE-2013-0011

  CVSS Scores

  Base 10 / Temporal 7.4

  Description

  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.

  A remote code execution vulnerability is caused when the Windows Print Spooler fails to handle a specially crafted print job.

  Microsoft has released a security update that addresses the vulnerability by correcting how the Windows Print Spooler handles specially crafted print jobs.

  This security update is rated Critical for all supported editions of Windows 7 and Windows Server 2008 R2.

  Consequence

  An attacker who successfully exploits this vulnerability could run arbitrary code on a user's system with system privileges and take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts.

  February 2013 Security Updates Are on MyOEM and ECE for XPe SP3 and Standard 2009 (KB2757638)
  

  Consequence

  The vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker would have no way to force users to visit such a website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes the user to the attacker's website.

  Solution

  Refer to MS13-002 for more information.

  Workaround:
  1) Restrict access to msxml3.dll or msxml6.dll
