The remote Gentoo host is missing one or more security-related
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
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
Adan Barth (UC Berkely) and Collin Jackson (Stanford University)
discovered a flaw occurring when interpreting HTTP response headers
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
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,
The vendor reported an unspecified arbitrary code execution
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
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
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.
