![]() It released just one security bulletin for Adobe Substance 3D Painter to address 14 CVEs, 11 of which are rated critical and the rest important. Adobe's single security bulletinĪdobe, likewise, addressed a smaller-than-usual number of vulnerabilities in May. This is because, as Childs notes, "the Preview Pane is an attack vector." Also, while Outlook looks like the most likely exploit vector, it can affect other Office applications, so prioritize patching this one. Redmond says an attacker could exploit this flaw by sending a specially crafted email to the target, who opens it with a vulnerable version of Outlook or allows it to be displayed in a preview pane. Microsoft disarms push notification bombers with number matching in Authenticatorįinally, the publicly disclosed bug that has not (yet) been exploited (as far as we know) is CVE-2023-29325, a Windows OLE Remote Code Execution (RCE) vulnerability that received an 8.1 CVSS rating.Mirai botnet loves exploiting your unpatched TP-Link routers, CISA warns.Apple pushes first-ever 'rapid' patch – and rapidly screws up.It's official: BlackLotus malware can bypass Secure Boot on Windows machines. ![]() And by the first quarter of 2024, we'll have a final fix for the bug by default across all Windows devices. In July, Microsoft will issue a second release to simplify deployment of the patch. As security analyst Will Dorman quipped: "Feel free to cry a bit and/or consider a career change." While Microsoft released a fix, of sorts, for the Windows boot manager in today's patchapalooza to thwart the bootkit, the CVE-2023-24932 update is disabled by default and requires customers to manually update bootable media to fully implement the protections. The malware can disable antivirus defenses, and installs a kernel driver that receives commands from a control server to carry out, effectively placing a remote-control backdoor in the machine. By targeting weaknesses in this boot process, BlackLotus loads before anything else, including the operating system and any security tools that could stop it. Secure Boot is supposed to prevent devices from running unauthorized or malicious software before the operating system, such as Windows, executes. That functionality should instead block BlackLotus. This is significant because BlackLotus, a UEFI bootkit that's sold on hacking forums for about $5,000, is a rare malware strain in that it runs on Windows systems even with the Secure Boot firmware security feature enabled. Prior to that, Kaspersky's lead security researcher Sergey Lozhkin first saw BlackLotus being sold on cybercrime marketplaces back in October 2022. Redmond says ESET's Martin Smolár and SentinelOne's Tomer Sne-or disclosed the bug, and Smolár initially sounded the alarm on BlackLotus malware bypassing Secure Boot back in March. If also noted, however, that to successfully exploit this flaw, an attacker must have physical access or local admin privileges on the targeted device. "This is used by threat actors primarily as a persistence and defense evasion mechanism." "This vulnerability allows an attacker to execute self-signed code at the Unified Extensible Firmware Interface (UEFI) level while Secure Boot is enabled," MSRC warned. Meanwhile, CVE-2023-24932 received its own separate Microsoft Security Response Center (MSRC) advisory and configuration guidance, which Redmond says is necessary to "fully protect against this vulnerability." Redmond credited Avast bug hunters Jan Vojtešek, Milánek, and Luigino Camastra with finding and disclosing the bug.
