According to Adobe, smartphone users need to make sure to update their Flash player to the newest version, 10.3.185.23, because the previous version of 10.3 has a security flaw. The vulnerability allows a malicious software site to send you a fake email designed to trick you into clicking on a malicious link and further infecting your phone. Adobe's latest version fixes the problem, but it seems as if these security flaws with Flash are coming more frequently.
