Discussion

Adobe Flash Player Multimedia File Remote Buffer Overflow Vulnerability

Adobe Flash Player is prone to a remote buffer-overflow vulnerability when handling multimedia files with certain tags.

An attacker may exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in denial-of-service conditions.

Adobe Flash Player 9.0.115.0 and earlier versions are affected.

NOTE: This issue has been fixed in all versions of Adobe Flash Player 9.0.124.0.

Initial investigations suggested that the vulnerability had not been patched in the standalone Adobe Flash Player version 9.0.124.0 for Linux and the standalone Adobe Flash Player version 9.0.124.0 with debug capabilities for Microsoft Windows. The observed behavior that led to this initial conclusion has since been confirmed by Adobe as intended by design.

Exploit / POC

Adobe Flash Player Multimedia File Remote Buffer Overflow Vulnerability

"Application-Specific Attacks: Leveraging the ActionScript Virtual Machine", a paper by Mark Dowd of X-Force IBM ISS, describes in detail the techniques required to exploit this issue and serves as a proof of concept. Please see the references for more information.

An exploit and a proof of concept are available for members of Immunity's CANVAS Early Update Program:

https://www.immunityinc.com/downloads/immpartners/flash_duke.tgz
https://www.immunityinc.com/downloads/immpartners/CVE-2007-0071.tgz

Core Security Technologies has developed a working commercial exploit for its CORE IMPACT product. This exploit is not otherwise publicly available or known to be circulating in the wild.

Symantec has observed that this issue is being actively exploited in the wild.

UPDATE: Continued investigation reveals that this issue is fairly widespread. Malicious code is being injected into other third-party domains (approximately 20,000 web pages), most likely through SQL-injection attacks. The code then redirects users to sites hosting malicious Flash files exploiting this issue.

Solution / Fix
