We have always believed that reliable vulnerability intelligence and tools to aid identifying and fixing vulnerabilities should be freely available for consumers to ensure that users, who care about their online privacy and security, can stay secure. Only a few vendors address vulnerabilities in a proper way and help users get updated and stay secure. End-users (whether private individuals or businesses) are otherwise left largely alone, and that is why back in 2002, Secunia Research started investigating, coordinating disclosure and verifying software vulnerabilities. In 2016, Secunia Research became a part of Flexera and today our in-house software vulnerability research remains the core of the Software Vulnerability Management products at Flexera. https://secuniaresearch.flexerasoftware.com/community/research/ The public Secunia Advisory database contains information for researchers, security enthusiasts, and consumers to lookup individual products and vulnerabilities and assess, whether they need to take any actions to secure their systems or whether a given vulnerability has already been discovered https://secuniaresearch.flexerasoftware.com/community/advisories/ ====================================================================== 9) Verification Please verify this advisory by visiting the website: https://secuniaresearch.flexerasoftware.com/secunia_research/2017-19 ====================================================================== # 0day.today [2024-12-24] #
