vulnerability announce CVE-2014-1809

Microsoft Office: bypassing ASLR via MSCOMCTL

Synthesis of the vulnerability

An attacker can obtain memory addresses, to bypass ASLR, in order to facilitate the development of an attack tool.
Impacted products: Office, Access, Excel, InfoPath, OneNote, Outlook, PowerPoint, Project, Publisher, Visio, Word.
Severity: 2/4.
Consequences: data reading.
Provenance: document.
Creation date: 13/05/2014.
