CVE-2012-3725

Name of the Vulnerable Software and Affected Versions Apple iOS versions prior to 6

Description The issue concerns the DNAv4 protocol implementation in the DHCP component, which sends Wi-Fi packets containing a MAC address of a host on a previously used network. This might allow remote attackers to obtain sensitive information about previous device locations by sniffing an unencrypted Wi-Fi network for these packets.

Recommendations For Apple iOS versions prior to 6, update to iOS version 6 or later to resolve the issue.
