Title: Adobe Patches Vulnerabilities Under Active Exploitation in
Monthly Flash Player Security Bulletin
Description: Adobe has released their monthly Flash Player security
bulletin to address vulnerabilities, one of which is currently under
active exploitation in the wild. CVE-2016-4117 is a type-confusion
vulnerability that was originally reported to Adobe by FireEye. 24 other
security vulnerabilities were also addressed in the bulletin with the
the majority of them being use-after-free flaws and memory corruption
flaws that could lead to arbitrary code execution. Users are advised to
disable or remove Flash from their browser if it’s not necessary and to
otherwise patch as soon as possible if removal is not an option.
