CVE-2012-3725

TITLE

Apple iOS of DHCP Vulnerabilities that can capture important information in components

DESCRIPTION

The DNAv4 protocol implementation in the DHCP component in Apple iOS before 6 sends Wi-Fi packets containing a MAC address of a host on a previously used network, which might allow remote attackers to obtain sensitive information about previous device locations by sniffing an unencrypted Wi-Fi network for these packets. Apple iOS of DHCP In the component DNAv4 The protocol is implemented by the host on the network used immediately before. Successfully exploiting this issue will allow attackers to determine networks a device has previously accessed. Note: This issue was previously discussed in BID 55612 (Apple iPhone/iPad/iPod touch Prior to iOS 6 Multiple Vulnerabilities) but has been given its own record to better document it. Apple iOS is an operating system developed by Apple (Apple) for mobile devices. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2012-09-24-1 Apple TV 5.1 Apple TV 5.1 is now available and addresses the following: Apple TV Available for: Apple TV 2nd generation and later Impact: Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution Description: An uninitialized memory access existed in the handling of Sorenson encoded movie files.
