DESCRIPTION:
Multiple vulnerabilities have been reported in Apple iOS, which can
be exploited by malicious people bypass certain security
restrictions, conduct spoofing attacks, disclose sensitive
information, cause a DoS (Denial of Service), or to compromise a
user's system.

1) An error in the signature validation when handling configuration
profiles can result in a specially crafted, malicious configuration
profile appearing to have a valid signature.

2) Multiple vulnerabilities in FreeType can be exploited by malicious
people to potentially compromise an application using the library.

For more information:
SA34723
SA40586
SA40816
SA41738

3) An error in iAd Content Display in the handling of certain URL
schemes can be exploited to initiate a call without user
interaction.

Successful exploitation of this vulnerability requires manipulation
of a response for a requested ad.

4) Two vulnerabilities in libpng can be exploited by malicious people
to potentially compromise an application using the library.

For more information:
SA40302

5) An error in libxml can be exploited to potentially compromise an
application using the library.

For more information:
SA42175
 
6) An weakness in Mail can be exploited to trigger DNS prefetching
even if remote image loading is disabled.

7) A vulnerability in Networking can be exploited to cause system
shutdown.

For more information:
SA42151

8) An invalid pointer reference error in Networking when handling
packet filter rules can be exploited to gain system privileges.

9) An error in the Photos application can be exploited to disclose
the MobileMe account password.

Successful exploitation requires the attacker to manipulate a
response of the MobileMe Gallery requesting basic authentication.

10) A weakness is caused due to the "Reset Safari" feature taking up
to 30 seconds to clear the website passwords from memory.

11) A boundary error in the handling of Temporary Mobile Subscriber
Identity (TMSI) fields in GSM mobility management can be exploited to
cause a heap-based buffer overflow and execute arbitrary code on the
baseband processor.

12) Multiple vulnerabilities in WebKit can be exploited by malicious
people to compromise a user's system.

For more information:
SA40664
SA41085
SA42264

13) A design error within WebKit in the handling of the CSS
":visited" pseudo-class can be exploited to determine which sites a
user has visited.

SOLUTION:
Update to iOS 4.2 (downloadable and installable via iTunes).
