Title: Adobe Flash Player: Multiple vulnerabilities (GLSA 200801-07)
Severity: normal
Exploitable: remote
Date: January 20, 2008
Updated: May 28, 2009
Bug(s): #193519
ID: 200801-07

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: www-plugins/adobe-flash
Vulnerable: < 9.0.115.0
Unaffected: >= 9.0.115.0
Architectures: All supported architectures


Description

• 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).

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

Workaround

There is no known workaround at this time.

Resolution

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