Description

The version of Adobe Flash Player installed on the remote macOS or Mac OS X host is equal or prior to version 26.0.0.131. It is, therefore, affected by multiple vulnerabilities :

  • An information disclosure vulnerability exists due to an unspecified flaw. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a website containing specially crafted Flash content, to disclose sensitive information. (CVE-2017-3080)

  • A remote code execution vulnerability exists due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a website containing specially crafted Flash content, to execute arbitrary code. (CVE-2017-3099)

  • An information disclosure vulnerability exists that allows an unauthenticated, remote attacker to corrupt memory and disclose memory addresses. (CVE-2017-3100)
