Emergency Media Training: Facing a Reporter Within 2 Hours
This course will quickly teach you how to look your best on camera, prepare a message, develop a strategy for answering questions and create sound bites for that interview staring you in the face. This no-frills course gives you nothing but the bare essentials–you should be able to complete the course in 30 minutes or less. That way you will have more time to practice for your upcoming interview.
TJ Walker has trained more than 10,000 executives from six continents over the last 30 years including Presidents of countries, Prime Ministers, Nobel Peace Prize winners, Members of parliament, US Senators and Miss Universes. He will teach you the same techniques that leading executives pay top dollar for in one-on-one training sessions.
Reputations are often made or broken during the first few media interviews conducted during a crisis or breaking news story event. You do NOT want to learn through trial and error in front of thousands or even millions of viewer/listeners/readers.

Adobe issued out-of-band patches for critical flaws tied to 12 CVEs in Photoshop and other applications.
Adobe released a slew of patches for critical vulnerabilities Tuesday that were part of an out-of-band security update. Several of the critical flaws are tied to Adobe’s popular Photoshop photo-editing software and allow adversaries to execute arbitrary code on targeted Windows devices.
Overall, Adobe issued patches for flaws tied to 12 CVEs across Bridge, Prelude and Photoshop applications. The unscheduled updates come a week after Adobe issued its official July 2020 security updates, including critical code-execution bugs.
Adobe said it was not aware of any exploits in the wild for any of the bugs patched in the update. The company did not offer technical details regarding the Photoshop CVEs.
Threatpost reached out to Mat Powell, researcher with Trend Micro’s Zero Day Initiative, who is credited for finding each of the critical flaws. Powell has not responded to that request. Threatpost hopes to update this report with additional commentary from the researcher.
All of the reported critical flaws stem from out-of-bounds read and write vulnerabilities, which occur when the software reads data past the end of – or before the beginning of – the intended buffer, potentially resulting in corruption of sensitive information, a crash, or code execution among other things.
Adobe Photoshop features two out-of-bounds read flaws (CVE-2020-9683, CVE-2020-9686) and three out-of-bound write (CVE-2020-9684, CVE-2020-9685, CVE-2020-9687) issues. All of these could “lead to arbitrary code execution in the context of the current user,” according to Adobe.
The Photoshop vulnerabilities affect Photoshop CC 2019 versions 20.0.9 and earlier and Photoshop 2020 21.2 and earlier (for Windows). Users can update to versions 20.0.10 and 21.2.1, respectively.
Adobe has previously addressed various serious flaws in its Photoshop photo editing app, including dozens of arbitrary code-execution issues in March – which addressed 22 CVEs in Photoshop overall, 16 of which were critical.
Also fixed were critical flaws tied to three CVEs in Bridge, Adobe’s asset management app. These include an out-of-bounds read flaw (CVE-2020-9675) and out-of-bounds write issues (CVE-2020-9674, CVE-2020-9676) that could enable code execution. Adobe Bridge versions 10.0.3 and earlier are affected; users can update to version 10.1.1 for a fix.
Adobe also issued patches for critical vulnerabilities in its Prelude app, which works with its Premiere Pro video editing app to allow users to tag media with metadata for searching, post-production workflows, and footage lifecycle management.
Prelude contains out-of-bounds read (CVE-2020-9677, CVE-2020-9679) and out-of-bounds write (CVE-2020-9678, CVE-2020-9680) glitches that can allow code execution. Adobe Preluade versions 9.0 and earlier for Windows are affected; users can update to version 9.0.1.
Powell was also credited with reporting the additional critical flaws.
Adobe also issued patches for an “important” severity flaw in Adobe Reader Mobile for Android, which allows users to view and edit PDFs from their smartphones. The application has a directory traversal issue (CVE-2020-9663) enabling information disclosure in the context of the current user. Adobe Reader Mobile for Android, versions 20.0.1 and earlier are impacted. Users can update to version 20.3 (for all Android versions).

The patches fix two separate RCE bugs in Windows Codecs that allow hackers to exploit playback of multimedia files.
Microsoft has quietly pushed out two emergency security updates to fix remote code execution bugs in Microsoft Windows Codecs Library.
Windows Codecs Library handles how the OS compresses large multimedia files such as photos and videos, and then decodes them for playback within applications. The out-of-band updates, addressing a critical-severity flaw (CVE-2020-1425) and important-severity vulnerability (CVE-2020-1457), were sent out via Windows Update Tuesday night and affect several versions of Windows 10 and Windows Server 2019.
Both vulnerabilities allow for remote code execution “in the way that Microsoft Windows Codecs Library handles objects in memory,” according to the updates.

The rescue mode is also referred to as the single-user mode. As the name suggests, the rescue mode is used when you want to salvage your system from a system failure, for example, boot failure or reset a password. In rescue mode, all the local filesystems are mounted. However, only salient services are started. Normal services such as network services will not be started.
Emergency mode provides a minimal bootable environment and enables you to repair your Linux system even when rescue mode is not available. In emergency mode, only the root file system is mounted, and in read-only mode. Just as with rescue mode, only the essential services are activated in emergency mode.
