Description Tomas Hoger 2015-09-22 07:50:39 UTC 
Adobe Security Bulletin APSB15-23 for Adobe Flash Player describes multiple flaws that can possibly lead to disclosure of sensitive information or allow bypass of exploitation protections when Flash Player is used to play a specially crafted SWF file.

Quoting from the APSB15-23:

These updates include additional validation checks to ensure that Flash Player rejects malicious content from vulnerable JSONP callback APIs  (CVE-2015-5571). 

These updates resolve a memory leak vulnerability (CVE-2015-5576). 

These updates include further hardening to a mitigation to defend against vector length corruptions  (CVE-2015-5568). 

These updates resolve a security bypass vulnerability that could lead to information disclosure (CVE-2015-5572). 

These updates resolve a vulnerability that could be exploited to bypass the same-origin-policy and lead to information disclosure (CVE-2015-6679).
