Adobe Flash Player: Multiple vulnerabilities

1.  Gentoo Linux Security Advisory

Version Information

Related bugreports: #204344

Synopsis

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

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.

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.

3.  Resolution Information

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 --verbose ">=net-www/netscape-flash-9.0.124.0"
