However, Jonathan Kamens has discovered a fairly simple means by which a nefarious individual can trick Mail into automatically adding any address to the whitelist. Kamens says he reported the flaw to Apple back in June, but adds that the company has neither fixed the problem nor treated it as a security vulnerability. Fortunately for concerned parents, Kamens lays out a pair of stopgap workarounds.</div><!-- blurb inner --></div><!-- blurb outer -->

<div class="article_preview" id="blurb_11545" style="display:none"><div id="popup_inner_11545">Garmin is voluntarily recalling about 1.25 million n├╝vi GPS devices, nearly 800,000 of which were sold in the United States. The recall is to address a problem with the battery that could cause the device to overheat and become a fire hazard. Affected units include the n├╝vi 200W, 250W, 260W, and 7xx (where xx is a two-digit number), though apparently not the 255W we reviewed in 2008. Fewer than 10 cases of overheating have been identified, but Garmin will replace the battery and insert a spacer before returning your GPS, free of charge. </div><!-- blurb inner --></div><!-- blurb outer -->

There isn't much likelihood of this attack being used widely, because its utility requires either gaining control of the smartphone or the same password being used elsewhere, and the screen can easily be cleaned. But it's still interesting just where security vulnerabilities will be found.</div><!-- blurb inner --></div><!-- blurb outer -->
