This security advisory describes one critical risk vulnerability.
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to heap-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 results in arbitrary code execution on the vulnerable system.
Note: the vulnerability was being actively exploited.
Update the affected packages.
