VULNERABILITy TRENDS<br />
Commentary<br />
• All vulnerabilities dramatically increased in 2012, except<br />
Opera and Microsoft Internet Explorer, which saw a slight<br />
increase.<br />
• Chrome vulnerabilities increased dramatically in 2012<br />
(268). This could be due to the series of exploits developed<br />
to prove that Chrome is not unbreakable. After a spike in<br />
2010 (191), the documented vulnerabilities for Chrome<br />
browser dropped to 62 for 2011, which is a similar level<br />
as in previous years. Several bug bounty programs were<br />
organized in 2012, which has contributed to the exposure<br />
of a lot of Chrome vulnerabilities.<br />
• These five browsers combined had 891 reported<br />
vulnerabilities in total in 2012, which is a strong increase<br />
from 351 in 2011. This increase is due to dramatically<br />
increased vulnerabilities seen in Safari, Chrome, and<br />
Firefox.
