"Vulnerabilities in the Linux kernel fixed in 2012 went unpatched for more than two years on average, more than twice as long as it took to fix unpatched flaws in current Windows OSes, according security firm Trustwave.
Zero-day flaws — software vulnerabilities for which no patch is available — in the Linux kernel that were patched last year took an average of 857 days to be closed, Trustwave found. In comparison zero-day flaws in current Windows OSes patched last year were fixed in 375 days.
The gap in time between the patches being issued can partly be explained by the differing structures of open-source project communities and proprietary software vendors, according to John Yeo, director of TrustWave SpiderLabs for EMEA."http://www.zdnet.com/linux-trailed-windows-in-patching-zero-days-in-2012-report-says-7000011326/
