Of the 121 Microsoft bugs, 17 are considered critical. First, CVE-2022-34713, a remote code execution vulnerability in Microsoft Windows Support Diagnostic Tool that's under active attack.

Microsoft says that some of the Exchange Server flaws addressed as part of the August 2022 Patch Tuesday also require admins to manually enable Extended Protection on affected servers to fully block attacks. Remote attackers can exploit these Exchange bugs to escalate privileges in low-complexity attacks after tricking targets into visiting a malicious server using phishing emails or chat messages.

Today is Microsoft's August 2022 Patch Tuesday, and with it comes fixes for the actively exploited 'DogWalk' zero-day vulnerability and a total of 121 flaws. [...]

Browser synchronization abuse: Bookmarks as a covert data exfiltration channelTwo universal and seemingly innocuous browser features - the ability to create bookmarks and browser synchronization - make users' lives easier, but may also allow hackers to establish a covert data exfiltration channel. 6 ways your cloud data security policies are slowing innovation - and how to avoid thatAs practically every organization shifts from managing their data in network-based data centers to storing it in the cloud, cloud data security policies are created to secure this data in a cloud environment.

Looking ahead to next week, we have a server end-of-life and still more updates that can impact printers. There have been several updates to KB5005408 throughout the year to help administrators identify and manage these non-compliant printers.

VMware and experts alike are urging users to patch multiple products affected by a critical authentication bypass vulnerability that can allow an attacker to gain administrative access to a system as well as exploit other flaws. "Given the prevalence of attacks targeting VMware vulnerabilities and a forthcoming proof-of-concept, organizations need to make patching CVE-2022-31656 a priority," Claire Tillis, senior research engineer with Tenable's Security Response Team, said in an email to Threatpost.

VMware has released fixes for ten vulnerabilities, including CVE-2022-31656, an authentication bypass vulnerability affecting VMware Workspace ONE Access, Identity Manager and vRealize Automation, which the company considers critical and advises to patch or mitigate immediately.CVE-2022-31656 is an authentication bypass vulnerability affecting local domain users on VMware Workspace ONE Access, Identity Manager and vRealize Automation, that may allow an attacker with network access to the UI to obtain administrative access without the need to authenticate first.

VMware has warned admins today to patch a critical authentication bypass security flaw affecting local domain users in multiple products and enabling unauthenticated attackers to gain admin privileges. "This critical vulnerability should be patched or mitigated immediately per the instructions in VMSA," VMware warned.

The team behind LibreOffice has released security updates to fix three security flaws in the productivity software, one of which could be exploited to achieve arbitrary code execution on affected systems. Tracked as CVE-2022-26305, the issue has been described as a case of improper certificate validation when checking whether a macro is signed by a trusted author, leading to the execution of rogue code packaged within the macros.

Samba is a widely-used open source toolkit that not only makes it easy for Linux and Unix computers to talk to Windows networks, but also lets you host a Windows-style Active Directory domain without Windows servers at all. Anyone with a long enough memory will recall, probably without a tremendous amount of affection, hooking up OS/2 computers to share files using SMB over NetBIOS. Samba started life in the early 1990s thanks to the hard work of Australian open source pioneer Andrew Tridgell, who figured out from first principles how SMB worked so that he could implement a compatible version for Unix while he was busy with his PhD at the Australian National University.
