5 Companies That Dropped The Ball This Week


Adobe Vulnerabilities Open Users To Targeted Attacks

Alerts about dangerous vulnerabilities in popular software products seem to be a weekly occurrence these days. But the threat level was cranked up a notch this week because of a serious flaw in Adobe Reader.

Earlier this week researchers detected a pair of dangerous zero-day vulnerabilities in Adobe Reader that were being actively exploited in a series of targeted attacks with malicious PDF files. The vulnerabilities were the result of coding errors in every version of the software, including Reader X and Reader XI.

That incident came just after Adobe issued its second update in less than a week to its Flash Player to repair 17 critical vulnerabilities.
