Multiple vulnerabilities in Adobe Flash Player
CVE-2014-9163

Stack-based buffer overflow

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to stack-based buffer overflow when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

Wen Guanxing of Venustech, The Google Security Team and FireEye were working at the vulnerability.
FireEye dubbed the attack exploiting the vulnerability "Operation GreedyWonk".
The vulnerability was exploited to compromise sites of:

  • Peterson Institute for International
  • Economics American Research Center in Egypt
  • Smith Richardson Foundation
TrendMicro uses CVE-2014-0498 in some reports to cover exploit used in Operation GreedyWonk. But we believe this is the same vulnerability and we will refer to it as CVE-2014-0502.
