Adobe Flash Vulnerabilities

The Hacking Team, a group of digital activists, was hacked earlier this summer. Within the data that was compromised, three Adobe Flash vulnerabilities were discovered; CVE-2015-5123, CVE-2015-5122, CVE-2015-5119.

Adobe has patched two of the three vulnerabilities but has yet to release a patch for the third. While Adobe has committed to patching all three vulnerabilities by the end of the week, many organizations are putting protections in place. For example, Mozilla Firefox is now blocking Adobe Flash by default. The block will remain in place until a version is running that contains a patch for all three vulnerabilities.

Below are some additional tips to protect yourself from the Adobe Flash vulnerabilities:

– Make sure you have Symantec installed and updated! (
– Avoid using Adobe Flash. Please see below for instructions on how to disable Adobe Flash in your browser.
– If you must use flash, use Firefox or Chrome. Both have a built-in “sandbox” feature which “adds an additional layer of protection to your browser by protecting against malicious web pages that try to leave programmes on your computer, monitor your web activities or steal private information from your hard drive” (
