  - Security update to 25.0.0.171 (bsc#1038281), fixing the     following vulnerabilities advised under APSB17-15 :

  - Use-after-free vulnerability that could lead to code     execution (CVE-2017-3071).

  - Memory corruption vulnerabilities that could lead to     code execution (CVE-2017-3068, CVE-2017-3069,     CVE-2017-3070, CVE-2017-3072, CVE-2017-3073,     CVE-2017-3074).

The remote Windows host is missing security update KB4020821. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-3071)

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-3068, CVE-2017-3069, CVE-2017-3070,     CVE-2017-3072, CVE-2017-3073, CVE-2017-3074)

The version of Adobe Flash Player installed on the remote macOS or Mac OS X host is equal or prior to version 25.0.0.163. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists that allows an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-3071)

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-3068, CVE-2017-3069, CVE-2017-3070,     CVE-2017-3072, CVE-2017-3073, CVE-2017-3074)
