DESCRIPTION:
A weakness and multiple vulnerabilities have been reported in Apple
iOS, which can be exploited by malicious people with physical access
to bypass certain security restrictions and by malicious people to
disclose sensitive information, conduct cross-site scripting attacks,
bypass certain security restrictions, and compromise a user's device.

1) An error within the CFNetwork component when handling URLs can be
exploited to disclose sensitive information by tricking the user into
visiting a malicious website.

2) An integer underflow error within the HFS component when handling
HFS catalog files can be exploited by mounting a maliciously crafted
disk image.

3) A logic error within the kernel does not properly handle debug
system calls and can be exploited to bypass the sandbox
restrictions.

4) An integer overflow error within the libresolv library when
handling DNS resource records can be exploited to corrupt heap
memory.

For more information see vulnerability #21 in:
SA47843

5) A race condition error in the Passcode Lock component when
handling slide to dial gestures can be exploited to bypass the
Passcode Lock screen.

6) The weakness is caused due to the Private Browsing mode in Safari
not properly preventing recording of visits to certain sites using
the pushState or replaceState JavaScript methods.

7) An error within the Siri component when handling voice commands
can be exploited to bypass the screen lock and forward an open mail
message to an arbitrary recipient.

8) A format string error in the VPN component when handling racoon
configuration files can be exploited to execute arbitrary code via a
specially crafted racoon configuration file.

9) A cross-origin error in the WebKit component can be exploited to
bypass the same-origin policy and disclose a cookie by tricking the
user into visiting a malicious website.

10) An error within the WebKit component when handling drag-and-drop
actions can be exploited to conduct cross-site scripting attacks.

11) Multiple unspecified errors within the WebKit component can be
exploited to conduct cross-site scripting attacks.

12) Some vulnerabilities are caused due to a bundled vulnerable
version of WebKit.

For more information:
SA45698
SA46049
SA46308
SA46594
SA46815
SA47231

Successful exploitation of vulnerabilities #2, #4, #8, and #12 may
allow execution of arbitrary code.
