The vulnerabilities are confirmed in version 0.18.5 and reported in versions prior to 0.18.6. ====================================================================== 4) Solution Update to version 0.18.6. ====================================================================== 5) Time Table 2017/12/04 - Maintainer contacted with the vulnerability details. 2017/12/04 - Maintainer confirmed the vulnerability. 2017/12/06 - Maintainer released a fix. 2017/12/07 - Release of Secunia Advisory SA76000. 2017/12/08 - Public disclosure of Secunia Research Advisory. ====================================================================== 6) Credits Laurent Delosieres, Secunia Research at Flexera Software. ====================================================================== 7) References The Flexera Software CNA has assigned the CVE-2017-16909 and CVE-2017-16910 identifiers for the vulnerabilities through the Common Vulnerabilities and Exposures (CVE) project. ====================================================================== 8) About Flexera Software Flexera helps application producers and enterprises increase application usage and the value they derive from their software. http://www.flexerasoftware.com/enterprise/company/about/ Flexera delivers market-leading Software Vulnerability Management solutions enabling enterprises to proactively identify and remediate software vulnerabilities, effectively reducing the risk of costly security breaches. http://www.flexerasoftware.com/enterprise/products/ Flexera supports and contributes to the community in several ways. 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 ======================================================================
