An improper certificate validation in the Lync for Mac 2011 can be exploited remotely to bypass security restrictions;
Memory corruption vulnerabilities can be exploited remotely via a specially designed file or website to execute arbitrary code in the context of current user;
An improper disclosure of memory contents can be exploited remotely via a specially designed document to obtain sensitive information;
An unknown vulnerability can be exploited remotely via a specially designed file to cause a denial of service;
An out-of-bounds read due to an uninitialized variable can be exploited remotely via a specially designed file to obtain sensitive information.

Technical details

Vulnerability (1) can be exploited by an authenticated attacker;

Exploiting vulnerability (2) requires intercepting and tampering with network traffic.
