Adobe Fixes Another Zero-Day Flaw in Its Flash Player
Adobe rushes an out-of-band patch for its Flash Player to fix a zero-day vulnerability that already was being exploited in the wild.Adobe published an out-of-band security update on June 23, fixing a zero-day vulnerability in its Flash Player technology. Known as CVE-2015-3113, the security flaw potentially could enable an attacker to take control of the system. "Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks," Adobe warned in its security bulletin. "Systems running Internet Explorer for Windows 7 and below, as well as Firefox on Windows XP, are known targets." Adobe credits security firm FireEye with responsibly reporting the flaw and helping get it fixed. FireEye's operations in Singapore first noticed earlier this month that the flaw was being used in a phishing campaign it is calling Operation Clandestine Wolf. Operation Clandestine Wolf is being attributed to a China-based hacker group that FireEye has labeled as APT3. FireEye had previously linked APT3 to another zero-day set of attacks in April that make use of previously unknown flaws in Microsoft's Internet Explorer browser.
FireEye explained in a blog post that CVE-2015-3113 is a bug in how the Flash Player parses Flash Video (FLV) files. Flash, as well as the Microsoft Windows-based operating systems on which it runs, has multiple protections in place to defend against attacks, which were all bypassed by the CVE-2015-3113 vulnerability.
