November 2019 Patch Tuesday: What to Expect

Microsoft has released 74 updates today – there are 13 Critical and 61 Important updates to deal with.

CVE-2019-1429 has been released to solve a bug that is being weaponized! This vulnerability should be treated as an ‘Out-of-Band’ update for anyone still using Internet Explorer. Previously, we have suggested moving away from IE—this is yet another reason to look for a safer browser for your business.

Robert Brown, Director of Services for Syxsense said, “The biggest risk our customers can take, is not treating weaponized vulnerabilities seriously enough. Weaponized vulnerabilities are often not the highest severity and aren’t prioritized enough by IT managers and security administrators. In this case, the severity is critical. If the vulnerability was exploited, it could easily be used to spread ransomware or take over a system. Please patch this now.”

Not Critical, But High Priority Patches

CVE-2019-1384 and CVE-2019-1424 have only been ranked as Important by Microsoft, however the independent CVSS Score has ranked these 8.5 and 8.1 respectively. CVE-2019-1384 is a vulnerability impacting all Windows operating systems from Windows 7 to Windows Server 2019 where an attacker could obtain key and sign in messages making some security login audit records redundant. It can also infect other machines.

We believe CVE-2019-1424 is particularly dangerous. If exposed, this vulnerability could downgrade the secure communications channel leading to communications messages being sent to Windows improperly—possibly even intercepted and recorded.

Latest Adobe Patches

Adobe released four patches for Adobe Animate CC, Illustrator CC, Bridge CC, and Media Encoder. The Media Encoder patch includes a critical fix for an out-of-bounds (OOB) that could allow code execution. Both Syxsense and Adobe recommend this Out-of-Band update be deployed within the next 7 days.
