Adobe Flash Player: Multiple vulnerabilities

Adobe Flash Player: Multiple vulnerabilities Multiple vulnerabilities have been identified, the worst of which allow arbitrary code execution on a user's system via a malicious Flash file. adobe-flash 2009-03-10 2009-05-28 239543 251496 260264 remote 10.0.22.87 10.0.22.87

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.

Multiple vulnerabilities have been discovered in Adobe Flash Player:

The access scope of SystemsetClipboard() allows ActionScript programs to execute the method without user interaction (CVE-2008-3873).
The access scope of FileReference.browse() and FileReference.download() allows ActionScript programs to execute the methods without user interaction (CVE-2008-4401).
The Settings Manager controls can be disguised as normal graphical elements. This so-called "clickjacking" vulnerability was disclosed by Robert Hansen of SecTheory, Jeremiah Grossman of WhiteHat Security, Eduardo Vela, Matthew Mastracci of DotSpots, and Liu Die Yu of TopsecTianRongXin (CVE-2008-4503).
Adan Barth (UC Berkely) and Collin Jackson (Stanford University) discovered a flaw occurring when interpreting HTTP response headers (CVE-2008-4818).
Nathan McFeters and Rob Carter of Ernst and Young's Advanced Security Center are credited for finding an unspecified vulnerability facilitating DNS rebinding attacks (CVE-2008-4819).
When used in a Mozilla browser, Adobe Flash Player does not properly interpret jar: URLs, according to a report by Gregory Fleischer of pseudo-flaw.net (CVE-2008-4821).
Alex "kuza55" K. reported that Adobe Flash Player does not properly interpret policy files (CVE-2008-4822).
The vendor credits Stefano Di Paola of Minded Security for reporting that an ActionScript attribute is not interpreted properly (CVE-2008-4823).
Riley Hassell and Josh Zelonis of iSEC Partners reported multiple input validation errors (CVE-2008-4824).
The aforementioned researchers also reported that ActionScript 2 does not verify a member element's size when performing several known and other unspecified actions, that DefineConstantPool accepts an untrusted input value for a "constant count" and that character elements are not validated when retrieved from a data structure, possibly resulting in a null-pointer dereference (CVE-2008-5361, CVE-2008-5362, CVE-2008-5363).
The vendor reported an unspecified arbitrary code execution vulnerability (CVE-2008-5499).
Liu Die Yu of TopsecTianRongXin reported an unspecified flaw in the Settings Manager related to "clickjacking" (CVE-2009-0114).
The vendor credits Roee Hay from IBM Rational Application Security for reporting an input validation error when processing SWF files (CVE-2009-0519).
Javier Vicente Vallejo reported via the iDefense VCP that Adobe Flash does not remove object references properly, leading to a freed memory dereference (CVE-2009-0520).
Josh Bressers of Red Hat and Tavis Ormandy of the Google Security Team reported an untrusted search path vulnerability (CVE-2009-0521).

A remote attacker could entice a user to open a specially crafted SWF file, possibly resulting in the execution of arbitrary code with the privileges of the user or a Denial of Service (crash). Furthermore a remote attacker could gain access to sensitive information, disclose memory contents by enticing a user to open a specially crafted PDF file inside a Flash application, modify the victim's clipboard or render it temporarily unusable, persuade a user into uploading or downloading files, bypass security restrictions with the assistance of the user to gain access to camera and microphone, conduct Cross-Site Scripting and HTTP Header Splitting attacks, bypass the "non-root domain policy" of Flash, and gain escalated privileges.

There is no known workaround at this time.

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