APPLE-SA-2008-06-19 Safari v3.1.2 for Windows
Safari v3.1.2 for Windows is now available and addresses the
following issues:
Safari
CVE-ID: CVE-2008-1573
Available for: Windows XP or Vista
Impact: Viewing a maliciously crafted BMP or GIF image may lead to
information disclosure
Description: An out-of-bounds memory read may occur in the handling
of BMP and GIF images, which may lead to the disclosure of memory
contents. This update addresses the issue by performing additional
validation of BMP and GIF images. This issue is addressed in systems
running Mac OS X v10.5.3, and in Mac OS X v10.4.11 with Security
Update 2008-003. Credit to Gynvael Coldwind of Hispasec for reporting
this issue.
Safari
CVE-ID: CVE-2008-2540
Available for: Windows XP or Vista
Impact: Saving untrusted files to the Windows desktop may lead to
the execution of arbitrary code
Description: An issue exists in how the Windows desktop handles
executables. Saving an untrusted file to the Windows desktop may
trigger the issue, and lead to the execution of arbitrary code. Web
browsers are a means by which files may be saved to the desktop. To
help mitigate this issue, the Safari browser has been updated to
prompt the user prior to saving a download file. Also, the default
download location is changed to the user's Downloads folder on
Windows Vista, and to the user's Documents folder on Windows XP. This
issue does not exist on systems running Mac OS X. Additional
information is available from
http://www.microsoft.com/technet/security/advisory/953818.mspx which
credits Aviv Raff with reporting the issue.
Safari
CVE-ID: CVE-2008-2306
Available for: Windows XP or Vista
Impact: Visiting a malicious website which is in a trusted Internet
Explorer zone may lead to the automatic execution of arbitrary code
Description: If a website is in an Internet Explorer 7 zone with the
"Launching applications and unsafe files" setting set to "Enable", or
if a website is in the Internet Explorer 6 "Local intranet" or
"Trusted sites" zone, Safari will automatically launch executable
files that are downloaded from the site. This update addresses the
issue by not automatically launching downloaded executable files, and
by prompting the user before downloading a file if the "always
prompt" setting is enabled. This issue does not exist on systems
running Mac OS X. Credit to Will Dormann of CERT/CC for reporting
this issue.
WebKit
CVE-ID: CVE-2008-2307
Available for: Windows XP or Vista
Impact: Visiting a maliciously crafted website may lead to an
unexpected application termination or arbitrary code execution
Description: A memory corruption issue exists in WebKit's handling
of JavaScript arrays. Visiting a maliciously crafted website may lead
to an unexpected application termination or arbitrary code execution.
This update addresses the issue through improved bounds checking.
