This month alone, the MSVR (Microsoft Security Vulnerability Research) team released advisories to document vulnerabilities in WordPress and Apple's Safari browser and in July, software flaws were found and fixed in Google Picasa and Facebook.
The MSVR program, launched two three years ago, gives Microsoft researchers freedom to audit the code of third-party software and work in a collaborative way with the affected vendor to get those issues fixed before they are publicly compromised.
Since July 2010, Microsoft said the MSVR team identified and responsibly disclosed 109 different software vulnerabilities affecting a total of 38 vendors.
More than 93 percent of the third-party vulnerabilities found through MSVR since July 2010 were rated as Critical or Important, the company explained.
"Vendors have responded and have coordinated on 97 percent of all reported vulnerabilities; 29 percent of third-party vulnerabilities found since July 2010 have already been resolved, and none of the vulnerabilities without updates have been observed in any attacks," Microsoft said.
