This month’s Patch Tuesday is rather light and addresses 36 vulnerabilities, with only 7 labeled as Critical. Five of the seven Critical vulns are in Git for Visual Studio. The others are for Hyper-V and Win32k. Also, there is one actively attacked “Important” vuln in Win32k. Adobe released patches today covering Acrobat/Reader, ColdFusion, Photoshop, and Brackets.
This month’s Microsoft Patch Tuesday addresses 74 vulnerabilities with 13 of them labeled as Critical. Of the 13 Critical vulns, 5 are for browsers and scripting engines. Out of the 8 remaining Critical vulns, 4 are potential hypervisor escapes in Hyper-V, as well as vulnerabilities in Microsoft Exchange, Win32k, Windows Media Foundations, and OpenType. Adobe’s Patch Tuesday was on time this month, and covers 11 vulns spread across Animate, Illustrator, Media Encoder, and Bridge.
UPDATE
There are reports that the CVE-2019-1402 patches are causing issues with all supported versions of Microsoft Access. Microsoft has posted a document on the issue with upcoming fix dates and workarounds.
This month’s Microsoft Patch Tuesday addresses 59 vulnerabilities with only 9 of them labeled as Critical. Of the 9 Critical vulns, 7 of them are for browsers and scripting engines. The remaining 2 are for Azure App Service and Remote Desktop Client. In addition, PoC code has been published for an Important Windows Error Reporting vulnerability. Adobe has not posted any patches for Patch Tuesday, but did issue out-of-band patches for ColdFusion on September 24th.
This month’s Microsoft Patch Tuesday addresses 79 vulnerabilities with 17 of them labeled as Critical. Of the 17 Critical vulns, 8 are for scripting engines and browsers, 4 are for the Remote Desktop Client, and 3 are for SharePoint. In addition, Microsoft has again patched a critical vulnerability in LNK files, along with a vuln in Azure DevOps / TFS. Adobe has also released patches for Flash and Application Manager.
Update: Following Patch Tuesday, Microsoft updated the entries for CVE-2019-1214 and CVE-2019-1215 to remove the “exploited” label.
Update Aug 13, 2019: Detect and Patch Windows Remote Desktop Vulnerabilities
This month’s Microsoft Patch Tuesday addresses 93 vulnerabilities with 29 of them labeled as Critical. Of the 29 Critical vulns, 10 are for scripting engines and browsers, 6 for Windows Graphics/Font Library, and 4 are for Office apps. In addition, Microsoft has patched 4 (!) Critical RCEs in Remote Desktop (plus 3 Important), 2 for Hyper-V, 2 in DHCP Client/Server, and one for LNK files. Adobe has also released a large number of patches covering multiple products.
This month’s Microsoft Patch Tuesday addresses 77 vulnerabilities with 15 of them labeled as Critical. Of the 15 Critical vulns, 11 are for scripting engines and browsers, with the remaining four covering DHCP Server, GDI+, .NET Framework, and Azure DevOps Server / Team Foundation Server. In addition, Microsoft has released Important patches for two actively exploited privilege escalation vulnerabilities, as well as a SQL Server RCE. Microsoft also issued two advisories for Outlook on the web and Linux Kernel vulnerabilities. Adobe issued patches today for Bridge CC, Experience Manager, and Dreamweaver.
Last week, Qualys issued a security advisory for a vulnerability we discovered during a code review of Exim. This vulnerability can lead to Remote Command Injection, and is currently being actively attacked in the wild. This blog will show you how to quickly identify assets that are impacted by this vulnerability.
This month’s Microsoft Patch Tuesday addresses 88 vulnerabilities with 21 of them labeled as Critical. Of the 21 Critical vulns, 17 are for scripting engines and browsers, and 3 are potential hypervisor escapes in Hyper-V. The remaining vulnerability is an RCE in the Microsoft Speech API. Microsoft also issued guidance on Bluetooth Low Energy FIDO keys, HoloLens, and Microsoft Exchange. Adobe issues patches today for Flash, ColdFusion, and Campaign.
Vulnerabilities that vendors have disclosed and issued patches for remain a major source of breaches. Why? Too many organizations take too long to deploy those patches — or never do.
That was the case with WannaCry. The ransomware exploited Windows vulnerability MS17-010, which Microsoft disclosed in mid-March 2017, rating it “Critical” and issuing a patch for it. The attacks began two months later. It was only then that most affected organizations began to install the patch. When the dust cleared, WannaCry had infected 300,000-plus systems, disrupting critical operations globally.
So why does this baffling problem persist?
As is true for most IT and security challenges, the patch management problem and its solution depend on a combination of the technology being used and of the processes in place.
Read on to learn about patch management best practices, and about Qualys’ new patch management cloud app.
This month’s Microsoft Patch Tuesday included a very high-risk vulnerability (CVE-2019-0708, aka BlueKeep) in Remote Desktop that impacts Windows XP, Windows 7, Server 2003, Server 2008, and Server 2008 R2. This vulnerability allows an unauthenticated attacker (or malware) to execute code on the vulnerable system. It is very likely that PoC code will be published soon, and this may result in a WannaCry-style attack.
Microsoft has not only released patches for Windows 7, Server 2008 & R2, but also has taken the extra step to issue patches for Windows XP and Server 2003. Patch now!
UPDATE: Network Level Authentication (NLA) partially mitigates this vulnerability. QID 90788 (Microsoft Windows Network Level Authentication Disabled) can be used to find hosts that have NLA disabled. This forces the attacker to have valid credentials in order to perform RCE.
UPDATE: A new remote (unauthenticated) check was released under QID 91541. See below for details.
