The version of Microsoft Edge installed on the remote host is missing Cumulative Security Update 3081436. It is, therefore, affected by multiple vulnerabilities :
Multiple memory corruption issues exist due to improper access to objects in memory resulting from insufficient validation of user-supplied input. A remote attacker, using a specially crafted website, can exploit these issues to execute arbitrary code in the context of the current user. (CVE-2015-2441, CVE-2015-2442, CVE-2015-2446)
A security feature bypass vulnerability exists due to a failure to use Address Space Layout Randomization (ASLR). An attacker can exploit this to predict memory offsets in a call stack. (CVE-2015-2449)
