<title>Adobe Flash Player: Multiple vulnerabilities</title>
Multiple vulnerabilities have been identified, the worst of which allow
arbitrary code execution on a user's system via a malicious Flash file.

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.
<li>Flash contains a copy of PCRE which is vulnerable to a heap-based
buffer overflow (GLSA 200711-30, CVE-2007-4768).</li>
<li>Aaron Portnoy reported an unspecified vulnerability related to
input validation (CVE-2007-6242).</li>
<li>Jesse Michael and Thomas Biege reported that Flash does not
correctly set memory permissions (CVE-2007-6246).</li>
<li>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).</li>
<li>David Neu reported an error withing the implementation of the
Socket and XMLSocket ActionScript 3 classes (CVE-2007-4324).</li>
<li>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).</li>
<li>Rich Cannings reported a cross-site scripting vulnerability in the
way the "asfunction:" protocol was handled (CVE-2007-6244).</li>
<li>Toshiharu Sugiyama discovered that Flash allows remote attackers to
modify HTTP headers for client requests and conduct HTTP Request
Splitting attacks (CVE-2007-6245).</li>
<impact type="normal">
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.
There is no known workaround at this time.
All Adobe Flash Player users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-plugins/adobe-flash-;</code>
Please be advised that unaffected packages of the Adobe Flash Player
have known problems when used from within the Konqueror and Opera
