A zero-day vulnerability is a software defect that doesn’t yet have a patch from the vendor. One of these currently exists for Adobe Flash Player, and it is being actively targeted by a working exploit. This particular defect (CVE-2018-4878) is a use-after-free vulnerability which allows remote code execution. This means that Flash Player tries to read instructions from a memory address that is no longer valid, and that the exploit is able to put malicious code at that memory address, causing Flash Player to execute the malicious code introduced by the exploit.
South Korean security researchers say that North Korea developed this exploit and have embedded it in Microsoft Word documents in an effort to attack South Koreans doing security research on North Korea, and that this has been going on for two or three months.
This zero-day started making news on 1 February, and Adobe says it’ll release a patch the week of 5 February. As in this case, it can take the vendor a while to address a defect like this. So if your character needs to compromise someone’s computer, she might search Dark Web forums for a recent zero-day like this and send it to her target in a phishing email, especially if she knows that her target is not diligent about keeping their computer up-to-date.
And if you use Flash Player, make sure you apply the patch when Adobe releases it. Version 22.214.171.124 is the affected version.
If you can stop playing Pokemon Go for a few minutes, you might head over to the Adobe download page and run your updates. Adobe’s July 2016 security bulletin lists a long number of critical vulnerabilities.
Adobe has released an update to flash player. This is an important update which addresses several security problems, one of which is being actively exploited. So if you have flash installed, you may want to head over to the flash player home page for an update. And here’s the Adobe security bulletin.
It was the second Tuesday of the month this week, so Microsoft has released updates to its products. Microsoft characterizes some of these updates as critical. Here’s the April 2016 Microsoft security bulletin.
Adobe has updated its April 2016 security bulletin from last week’s out-of-band announcement. The updated bulletin adds some new items that need updates.
WordPress has released version 4.5. That looks like more of a feature update than a security update. Still, if you host your own wordpress blog, you should probably update. (If, like me, your wordpress blog is hosted on the wordpress.com servers, you don’t need to do anything.)
And if you happen to run SAMBA on Linux (or similar), you need to run your updates, too. There’s a new man-in-the-middle exploit called Badlock which is getting some attention.
Adobe has released an update for flash player (here’s the security bulletin). Like Microsoft, Adobe usually release updates on the second Tuesday of the month (and they both did that earlier this week), but this update addresses serious problems in flash player, one of which is being actively exploited.
This is sometimes called an out-of-band update, because they’re releasing it off their normal schedule. That sometimes highlights the importance of the update.
So. Update your flash player.
Today Adobe and Microsoft have released updates to their software to address critical vulnerabilities. Here’s the Adobe bulletin (it covers updates to Acrobat and Reader), and here’s the Microsoft bulletin (it covers updates to Internet Explorer, Edge, Office, .Net, and other components).
Microsoft and Adobe both released software updates today to address long lists of software defects, many of which the vendors categorize as critical.
Microsoft and Adobe have released software updates for Microsoft Windows, Adobe Reader, and Adobe Acrobat. Both vendors rank these updates as critical.
Here’s Adobe’s security bulletin, and here’s the Microsoft security bulletin.
Adobe has released updates to Adobe Flash Player. This update addresses critical security problems. If you you have Flash Player installed on your computer (which is likely), please update it.
Looks like if you let Firefox and Google Chrome update themselves, that may be enough to update Flash Player in those browsers. Otherwise, the Adobe Flash Player page can tell you if you need an update (you may want to visit this page in each web browser you use).
For more technical information, see the Adobe security bulletin.
This bulletin also includes an update for Adobe AIR. If you think AIR is installed on your computer, here’s the Adobe AIR page.
