CVE-ID: CVE-2009-1704
Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11,
Mac OS X v10.5.7, Mac OS X Server v10.5.7, Windows XP or Vista
Impact: Downloaded image files may be misidentified as HTML, leading
to JavaScript execution without warning the user
Description: Image files are 'safe' types that, once downloaded, are
displayed by Safari without warning the user. An issue in Safari may
cause it to be unable to identify the file type of certain local
image files. In this case, Safari will examine the content of those
files and may treat them as HTML. If a file contains JavaScript, it
will be executed in the local context. For a downloaded file, this
should not occur without first prompting the user. This issue is
addressed by treating files of unknown type as generic binary data,
and by correctly identifying the image file types known to have this
issue. Credit to Sergio 'shadown' Alvarez of Recurity Labs GmbH for
