A vulnerability in Adobe Flash Player could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to improper memory operations performed by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by persuading a user to open a malicious link designed with crafted Flash content. A successful exploit could allow an attacker to execute arbitrary code with the privileges of the browser. If the browser runs with elevated privileges, an attacker could completely compromise the system.
Adobe has confirmed the vulnerability in a security bulletin and software updates are available.
Indicators of Compromise

Technical description is not available.
To exploit this vulnerability, an attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the link. This access requirement could reduce the likelihood of a successful exploit.
The vendor report indicates that the vulnerability is actively being exploited in the wild.
