GLSA-200903-23 : Adobe Flash Player: Multiple vulnerabilities

Description

The remote host is affected by the vulnerability described in GLSA-200903-23 (Adobe Flash Player: Multiple vulnerabilities) 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). Impact : 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. Workaround : There is no known workaround at this time.
