Version Summary:Functional code that demonstrates an exploit of the Adobe Flash Player remote code execution vulnerability is publicly available.
 
 
Description
A vulnerability in Adobe Flash Player could allow an unauthenticated, remote attacker to execute arbitrary code.

The vulnerability is due to improper memory operations performed when processing malicious Flash content. An attacker could exploit this vulnerability by convincing a targeted user to view malicious Flash content on a remote website. An exploit could allow the attacker to execute arbitrary code on the targeted system.

Functional code that exploits this vulnerability is available as part of the Metasploit framework.

Adobe has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
Adobe Flash Player versions 11.7.700.260 and prior and 12.0.0.43 and prior for Microsoft Windows and Apple Mac OS X are affected.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a file that contains embedded malicious SWF content to the user and attempt to convince the user to open or execute the file by using misleading language or instructions.

Reports indicate that the vulnerability is related to the previously reported zero-day attack. Adobe reports that attacks targeting this vulnerability have occurred in the wild.
 
Vendor Announcements
Adobe has released a security bulletin at the following link: APSB14-04

Red Hat has released an official CVE statement and a security advisory for bug 1061469 at the following links: CVE-2014-0497 and RHSA-2014:0137
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system with the privileges of the targeted user. If the user holds elevated privileges, the attacker could gain complete control over the system.
 
Technical Information
The vulnerability is due to improper parsing of certain Small Web Format (SWF) files by the affected software. The affected software fails to sanitize user-supplied input, which may trigger a integer underflow error and corrupt memory.

An unauthenticated, remote attacker could exploit the vulnerability by convincing a targeted user to open a crafted .swf file. When processed, the file could allow the attacker to trigger an integer underflow error, allowing the attacker to execute arbitrary code.
