Firefox, Adobe lead list of buggiest software

Firefox was the application that had the most reported vulnerabilities this year, while holes in Adobe software more than tripled from a year ago, according to statistics compiled by Qualys, a vulnerability management provider.

Qualys tallied 102 vulnerabilities that were found in Firefox this year, up from 90 last year. The numbers are based on running totals in the National Vulnerability Database.

However, the high number of Firefox vulnerabilities does not necessarily mean the Web browser actually has the most bugs; it just means it has the most reported holes. Because the software is open source, all holes are publicly disclosed, whereas proprietary software makers, like Adobe and Microsoft, typically only publicly disclose holes that were found by researchers outside the company, and not ones discovered internally, Qualys Chief Technology Officer Wolfgang Kandek said late on Wednesday.

Meanwhile, Adobe took the second-place spot from Microsoft this year. The number of vulnerabilities in Adobe programs rose from 14 last year to 45 this year, while those in Microsoft software dropped from 44 to 41, according to Qualys. Internet Explorer, Windows Media Player and Microsoft Office together had 30 vulnerabilities.
