Opera issued an advisory this week for its eponymous browser detailing
a flaw in the way the software handles long links–a vulnerability that
could be exploited to run programs on a victim's system.

The patch
is a relative rarity for Opera, which consistently has the lowest
vulnerability count every year, but also has the lowest market share
among the major Internet browser for the Windows operating system. The
Opera browser had 7 documented vulnerabilities in the first half of
2006, compared to 47 for Mozilla's Firefox and 38 for Microsoft's
Internet Explorer, according to Symantec's Internet Security Threat Report.
