TITLE:
Apple iPhone / iPod touch Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA31074

VERIFY ADVISORY:
http://secunia.com/advisories/31074/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Spoofing, DoS, System access

WHERE:
>From remote

OPERATING SYSTEM:
Apple iPhone
http://secunia.com/product/15128/
Apple iPod touch
http://secunia.com/product/16074/

DESCRIPTION:
Some vulnerabilities have been reported in Apple iPhone and iPod
touch, which can be exploited by malicious people to conduct spoofing
and cross-site scripting attacks, cause a DoS (Denial of Service),
bypass certain security restrictions, or compromise a user's system.

1) An error in CFNetwork can be exploited to spoof secure websites
via 502 Bad Gateway errors from a malicious HTTPS proxy server.

2) A vulnerability in the handling of packets with an IPComp header
can be exploited to cause a DoS.

For more information:
SA29130

3) An error within Safari in the handling of Unicode ideographic
spaces can be exploited to spoof the URL of a trusted web site in the
address bar.

4) An error exists in Safari within the handling of self-signed or
invalid certificates. If a user clicks on the menu button while being
prompted to accept or reject such a certificate, Safari automatically
accepts the certificate on the next visit.

5) A signedness error in Safari when handling Javascript array
indices can be exploited to trigger an out-of-bounds memory access
and may allow execution of arbitrary code.

6) A vulnerability due to Safari ignoring Unicode Byte-order-Mark
(BOM) sequences when parsing web pages can be exploited to bypass
certain HTML and Javascript filtering mechanisms.

This is related to vulnerability #8 in:
SA20376

7) A vulnerability Safari can be exploited by malicious people to
compromise a vulnerable system.

For more information see vulnerability #3 in:
SA30775

8) An unspecified error exists in WebKit in the processing of
style-sheet elements. This can be exploited to cause a memory
corruption and may allow execution of arbitrary code when a user
visits a specially crafted web page.

9) An error in Safari when handling xml documents can be exploited by
malicious people to cause a DoS (Denial of Service).

For more information:
SA28444

10) An error in Safari when processing xml documents can potentially
be exploited by malicious people to compromise a user's system.

For more information:
SA30315

11) An unspecified error exists in JavaScriptCore's handling of
runtime garbage collection. This can be exploited to cause a memory
corruption and may allow execution of arbitrary code when a user
visits a specially crafted web page.

12) Some vulnerabilities in Safari can be exploited by malicious
people to conduct cross-site scripting attacks or potentially to
compromise a user's system.

For more information:
SA29846

The vulnerabilities are reported in iPhone version 1.0 through 1.1.4,
and iPod touch version 1.1 through 1.1.4.

SOLUTION:
Upgrade to version 2.0 (downloadable and installable via iTunes).
