Multiple vulnerabilities have been identified, the worst of which allow arbitrary code execution on a user's system via a malicious Flash file.

2.  Impact Information


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.


  • Flash contains a copy of PCRE which is vulnerable to a heap-based buffer overflow (GLSA 200711-30, CVE-2007-4768).
  • Aaron Portnoy reported an unspecified vulnerability related to input validation (CVE-2007-6242).
  • Jesse Michael and Thomas Biege reported that Flash does not correctly set memory permissions (CVE-2007-6246).
  • Dan Boneh, Adam Barth, Andrew Bortz, Collin Jackson, and Weidong Shao reported that Flash does not pin DNS hostnames to a single IP addresses, allowing for DNS rebinding attacks (CVE-2007-5275).
  • David Neu reported an error withing the implementation of the Socket and XMLSocket ActionScript 3 classes (CVE-2007-4324).
  • Toshiharu Sugiyama reported that Flash does not sufficiently restrict the interpretation and usage of cross-domain policy files, allowing for easier cross-site scripting attacks (CVE-2007-6243).
  • Rich Cannings reported a cross-site scripting vulnerability in the way the "asfunction:" protocol was handled (CVE-2007-6244).
  • Toshiharu Sugiyama discovered that Flash allows remote attackers to modify HTTP headers for client requests and conduct HTTP Request Splitting attacks (CVE-2007-6245).


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 establish TCP sessions with arbitrary hosts, bypass the Security Sandbox Model, obtain sensitive information, port scan arbitrary hosts, or conduct cross-site-scripting attacks.

3.  Resolution Information


There is no known workaround at this time.


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

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-plugins/adobe-flash-"

Please be advised that unaffected packages of the Adobe Flash Player have known problems when used from within the Konqueror and Opera browsers.
