Adobe Flash Player versions 26.0.0.137 and earlier have an exploitable type confusion vulnerability when parsing SWF files. Successful exploitation could lead to arbitrary code execution.

Versions of Adobe Flash Player prior to 26.0.0.151 are unpatched, and 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-2017-3085)
 - 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-2017-3106)

The remote host is affected by the vulnerability described in GLSA-201709-16 (Adobe Flash Player: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Adobe Flash Player.
      Please review the referenced CVE identifiers for details.
  Impact :
