Microsoft’s latest security report shows that the number of new vulnerabilities found in its software was lower in first half of the year than the last half of 2007, with the Windows Vista OS proving more resistant to exploits than XP. Microsoft reported 77 vulnerabilities from January to June compared to 116 for the last six months of 2007, according to the company’s fifth Security Intelligence Report.
The decline is in line with the software industry as a whole, which saw a 19% decrease in vulnerability disclosures compared to the first half of 2007, Microsoft said. However, those vulnerabilities considered highly severe rose 13%.
Exploit code was available for about a third of the 77 vulnerabilities; however, reliable exploit code is available for only eight of those 77.
