Adobe Systems has issued a mammoth security update with patches for a combined 36 vulnerabilities, one of which is currently under attack in the wild. The most critical flaw, CVE-2015-5119, could lead to code execution. Adobe’s Flash Player updates are available for Macintosh, Windows and Linux.
“Adobe is aware of a report that CVE-2015-5119 is being actively exploited in the wild,” said Adobe. As noted by Lucian Constantin over at PCWorld, cybercriminals began using the exploit just a day after it was leaked from a surveillance software developer. Constantin wrote:
The exploit was found by security researchers yesterday among the 400GB worth of files stolen recently from Hacking Team, an Italian company that develops and sells intrusion and surveillance software to government agencies.
Similarly, it took just one extra day for Adobe Systems to patch the vulnerability with today's release of Adobe Flash Player 18.104.22.168 for Mac and Windows.
Cybercriminals use Exploit Kits to attack known vulnerabilities in browser plug-ins, such as Flash Player and other Adobe software, and install malware on a victim’s computer. “These attacks are typically launched from compromised websites or through malicious advertisements,” warned Constantin.
