TITLE:
Apple iPod Touch Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA31823

VERIFY ADVISORY:
http://secunia.com/advisories/31823/

CRITICAL:
Highly critical

IMPACT:
Hijacking, Security Bypass, Spoofing, Exposure of sensitive
information, System access

WHERE:
>From remote

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

DESCRIPTION:
Multiple vulnerabilities have been reported in Apple iPod touch,
which can be exploited by malicious applications to bypass certain
security features and by malicious people to poison the DNS cache,
spoof TCP connections, or potentially compromise a user's device.

1) An error in the application sandbox causes it to not properly
enforce access restrictions between third-party applications. This
can be exploited by one application to read another application's
files.

2) Multiple errors exist in the included version of FreeType, which
potentially can be exploited by malicious people to execute arbitrary
code when accessing specially crafted font data.

For more information:
SA30600

3) mDNSResponder does not provide sufficient randomization, which can
be exploited to poison the DNS cache.

For more information:
SA30973

4) Generation of predictable TCP initial sequence numbers can be
exploited to spoof TCP connections or hijack sessions.

5) A use-after-free error in WebKit when handling CSS import
statements can potentially be exploited to execute arbitrary code via
a specially crafted website.

SOLUTION:
Update to version 2.1.

PROVIDED AND/OR DISCOVERED BY:
