Vista released 6 months and 27 security vulnerability patches at a lower speed than XP

According to data released on Thursday by Jones, Microsoft's security strategy Director, six months after Windows Vista was released, more security vulnerabilities were publicly disclosed but not corrected than Windows XP.
Of the 27 Vista defects disclosed, Microsoft fixed 12 vulnerabilities. Six months after XP was released, Microsoft's security team fixed 36 of the 39 publicly disclosed vulnerabilities.

Jones said, in general, Vista is better than XP. Compared with XP, Windows Vista continues to show a trend in reducing the total number of vulnerabilities and the number of high-risk vulnerabilities.

Jones pointed out that most uncorrected Vista vulnerabilities are not critical defects and only one high-risk vulnerability is not corrected.

Six months after XP was released, two high-risk vulnerabilities were not fixed. In the first six months of release, Microsoft fixed 23 high-risk XP defects, with Vista's number being 1.

Jones said that Vista has fewer vulnerabilities than operating systems such as Red Hat Enterprise Linux and Mac OS X.
