DESCRIPTION:
Multiple vulnerabilities have been reported in Apple iOS, which can
be exploited by malicious people to disclose certain sensitive
information, conduct spoofing attacks, and compromise a user's
device.

1) An error within the CFNetwork component when handling URLs can be
exploited to redirect a user to an incorrect server.

This is related to vulnerability #4 in:
SA46377

2) Multiple errors within the CoreGraphics component when handling
FreeType fonts can be exploited to corrupt memory.

3) A logic error within the mmap system call when checking valid flag
combinations can be exploited to bypass codesigning checks and execute
unsigned code.

Successful exploitation of this vulnerability requires that the user
is tricked into installing a malicious App.

4) An error within libinfo when handling DNS name lookups can be
exploited to spoof lookups.

Successful exploitation of vulnerabilities #2 and #3 may allow
execution of arbitrary code.

SOLUTION:
Apply iOS 5.0.1 Software Update (downloadable and installable via
iTunes).

PROVIDED AND/OR DISCOVERED BY:
2) Reported by the vendor.

The vendor credits:
1) Erling Ellingsen, Facebook.
