APPLE-SA-2008-07-11 iPhone 2.0 and iPod touch 2.0
iPhone 2.0 and iPod touch 2.0 are now available and address the
following issues:
CFNetwork
CVE-ID: CVE-2008-0050
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: A malicious proxy server may spoof secure websites
Description: A malicious HTTPS proxy server may return arbitrary
data to CFNetwork in a 502 Bad Gateway error, which could allow a
secure website to be spoofed. This update addresses the issue by not
returning the proxy-supplied data on an error condition.
Kernel
CVE-ID: CVE-2008-0177
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: A remote attacker may be able to cause an unexpected device
reset
Description: An undetected failure condition exists in the handling
of packets with an IPComp header. Sending a maliciously crafted
packet to a system configured to use IPSec or IPv6 may cause an
unexpected device reset. This update addresses the issue by properly
detecting the failure condition.
Safari
CVE-ID: CVE-2008-1588
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Unicode ideographic spaces may be used to spoof a website
Description: When Safari displays the current URL in the address
bar, Unicode ideographic spaces are rendered. This allows a
maliciously crafted website to direct the user to a spoofed site that
visually appears to be a legitimate domain. This update addresses the
issue by not rendering Unicode ideographic spaces in the address bar.
Safari
CVE-ID: CVE-2008-1589
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Visiting a maliciously crafted website may lead to the
disclosure of sensitive information
Description: When Safari accesses a website that uses a self-signed
or invalid certificate, it prompts the user to accept or reject the
certificate. If the user presses the menu button while at the prompt,
then on the next visit to the site, the certificate is accepted with
no prompt. This may lead to the disclosure of sensitive information.
This update addresses the issue through improved handling of
certificates. Credit to Hiromitsu Takagi for reporting this issue.
Safari
CVE-ID: CVE-2008-2303
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Visiting a maliciously crafted website may lead to an
unexpected application termination or arbitrary code execution
Description: A signedness issue in Safari's handling of JavaScript
array indices may result in an out-of-bounds memory access. Visiting
a maliciously crafted website may lead to an unexpected application
termination or arbitrary code execution. This update addresses the
issue by performing additional validation of JavaScript array
indices. Credit to SkyLined of Google for reporting this issue.
Safari
CVE-ID: CVE-2006-2783
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Visiting a maliciously crafted website may lead to cross-
site scripting
Description: Safari ignores Unicode byte order mark sequences when
parsing web pages. Certain websites and web content filters attempt
to sanitize input by blocking specific HTML tags. This approach to
filtering may be bypassed and lead to cross-site scripting when
encountering maliciously-crafted HTML tags containing byte order mark
sequences. This update addresses the issue through improved handling
of byte order mark sequences. Credit to Chris Weber of Casaba
Security, LLC for reporting this issue.
Safari
CVE-ID: CVE-2008-2307
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
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.

Safari
CVE-ID: CVE-2008-2317
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Visiting a maliciously crafted website may lead to an
unexpected application termination or arbitrary code execution
Description: A memory corruption issue exists in WebCore's handling
of style sheet elements. Visiting a maliciously crafted website may
lead to an unexpected application termination or arbitrary code
execution. This update addresses the issue through improved garbage
collection. Credit to Peter Vreudegnhil working with the TippingPoint
Zero Day Initiative for reporting this issue.
Safari
CVE-ID: CVE-2007-6284
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Processing an XML document may lead to a denial of service
Description: A memory consumption issue exists in the handling of
XML documents containing invalid UTF-8 sequences, which may lead to a
denial of service. This update addresses the issue by updating the
libxml2 system library to version 2.6.16.
Safari
CVE-ID: CVE-2008-1767
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Processing an XML document may lead to an unexpected
application termination or arbitrary code execution
Description: A memory corruption issue exists in the libxslt
library. Viewing a maliciously crafted HTML page may lead to an
unexpected application termination or arbitrary code execution.

WebKit
CVE-ID: CVE-2008-1590
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Visiting a maliciously crafted website may lead to an
unexpected application termination or arbitrary code execution
Description: A memory corruption issue exists in JavaScriptCore's
handling of runtime garbage collection. Visiting a maliciously
crafted website may lead to an unexpected application termination or
arbitrary code execution. This update addresses the issue through
improved garbage collection. Credit to Itzik Kotler and Jonathan Rom
of Radware for reporting this issue.
WebKit
CVE-ID: CVE-2008-1025
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Accessing a maliciously crafted URL may result in cross-site
scripting
Description: An issue exists in WebKit's handling of URLs containing
a colon character in the host name. Accessing a maliciously crafted
URL may lead to a cross-site scripting attack. This update addresses
the issue through improved handling of URLs. Credit to Robert Swiecki
of the Google Security Team, and David Bloom for reporting this
issue.
WebKit
CVE-ID: CVE-2008-1026
Available for: iPhone v1.0 through v1.1.4,
iPod touch v1.1 through v1.1.4
Impact: Viewing a maliciously crafted web page may lead to an
unexpected application termination or arbitrary code execution
Description: A heap buffer overflow exists in WebKit's handling of
JavaScript regular expressions. The issue may be triggered via
JavaScript when processing regular expressions with large, nested
repetition counts. This may lead to an unexpected application
termination or arbitrary code execution. This update addresses the
issue by performing additional validation of JavaScript regular
expressions. Credit to Charlie Miller of Independent Security
Evaluators for reporting this issue.
