Synopsis

========

 

Multiple vulnerabilities have been identified, the worst of which allow

arbitrary code execution on a user's system via a malicious Flash file.

 

Background

==========

 

The Adobe Flash Player is a renderer for the popular SWF file format,

which is commonly used to provide interactive websites, digital

experiences and mobile content.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-www/netscape-flash < 9.0.124.0 >= 9.0.124.0

 

Description

===========

 

Multiple vulnerabilities have been discovered in Adobe Flash:

 

* Secunia Research and Zero Day Initiative reported a boundary error

related to DeclareFunction2 Actionscript tags in SWF files

(CVE-2007-6019).

 

* The ISS X-Force and the Zero Day Initiative reported an unspecified

input validation error that might lead to a buffer overflow

(CVE-2007-0071).

 

* Microsoft, UBsecure and JPCERT/CC reported that cross-domain policy

files are not checked before sending HTTP headers to another domain

(CVE-2008-1654) and that it does not sufficiently restrict the

interpretation and usage of cross-domain policy files

(CVE-2007-6243).

 

* The Stanford University and Ernst and Young's Advanced Security

Center reported that Flash does not pin DNS hostnames to a single IP

addresses, allowing for DNS rebinding attacks (CVE-2007-5275,

CVE-2008-1655).

 

* The Google Security Team and Minded Security Multiple reported

multiple cross-site scripting vulnerabilities when passing input to

Flash functions (CVE-2007-6637).

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted file

(usually in a web browser), possibly leading to the execution of

arbitrary code with the privileges of the user running the Adobe Flash

Player. The attacker could also cause a user's machine to send HTTP

requests to other hosts, establish TCP sessions with arbitrary hosts,

bypass the security sandbox model, or conduct Cross-Site Scripting and

Cross-Site Request Forgery attacks.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Adobe Flash Player users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot -v ">=net-www/netscape-flash-9.0.124.0"
