The number of vulnerabilities in the first half of 2010 was close to the number recorded in the whole of 2009, security notification firm Secunia reports.
Apple ranks first, ahead of runner-up Oracle, and Microsoft in the number of security bugs found in all their products in 1H 2010. During the first six months of 2010, Secunia logged 380 vulnerabilities within the top-50 most prevalent packages on typical end-user PCs, or 89 per cent of the figure for the entire year of 2009.
