The vulnerability could allow security feature bypass if a user views a specially crafted webpage in a web browser capable of instantiating COM components, such as Internet Explorer. In a web-browsing attack scenario, an attacker who successfully exploited this vulnerability could bypass the Address Space Layout Randomization (ASLR) security feature, which helps protect users from a broad class of vulnerabilities. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use this ASLR bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability that could take advantage of the ASLR bypass to run arbitrary code. This security update is rated Important for supported editions of Microsoft Office 2007, Microsoft Office 2010, and Microsoft Office 2013. Affected Software Microsoft Office 2007 Microsoft Office 2010 Microsoft Office 2013 Microsoft Office 2013 RT Vulnerability Information MSCOMCTL ASLR Vulnerability - CVE-2014-1809 A security feature bypass vulnerability exists because the MSCOMCTL common controls library used by Microsoft Office software does not properly implement Address Space Layout Randomization (ASLR). The vulnerability could allow an attacker to bypass the ASLR security feature, which helps protect users from a broad class of vulnerabilities. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use this ASLR bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability that could take advantage of the ASLR bypass to run arbitrary code. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
