Description: 

Adobe Flash Player is prone to multiple vulnerabilities. These vulnerabilities are as follows:

  • These updates resolve heap buffer overflow vulnerabilities that could lead to code execution (CVE-2015-5129, CVE-2015-5541)
  • These updates resolve use-after-free vulnerabilities that could lead to code execution (CVE-2015-5550, CVE-2015-5551, CVE-2015-3107, CVE-2015-5556, CVE-2015-5130, CVE-2015-5134, CVE-2015-5539, CVE-2015-5540, CVE-2015-5557, CVE-2015-5559, CVE-2015-5127, CVE-2015-5563, CVE-2015-5561, CVE-2015-5124)
  • These updates resolve buffer overflow vulnerabilities that could lead to code execution (CVE-2015-5131, CVE-2015-5132, CVE-2015-5133)
  • These updates resolve memory corruption vulnerabilities that could lead to code execution (CVE-2015-5544, CVE-2015-5545, CVE-2015-5546, CVE-2015-5547, CVE-2015-5548, CVE-2015-5549, CVE-2015-5552, CVE-2015-5553).Type confusion vulnerability that could lead to code execution (CVE-2015-5128, CVE-2015-5554, CVE-2015-5555, CVE-2015-5558, CVE-2015-5562)
  • Security bypass vulnerability that could lead to information disclosure (CVE-2015-3114)
  • These updates include further hardening to a mitigation introduced in version 18.0.0.209 to defend against vector length corruptions (CVE-2015-5125)
  • These updates resolve an integer overflow vulnerability that could lead to code execution (CVE-2015-5560)

Successful exploitation of these vulnerabilities could result in an attacker compromising data security, potentially allowing access to confidential data, or could compromise processing resources in a user's computer.

Actions: 
  • Install the updates provided by Adobe immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments, especially those from un-trusted sources.
