Flash, Windows Users: It’s Time to Patch

Adobe and Microsoft each pushed critical security updates to their products today. Adobe’s got a new version of Flash Player available, and Microsoft released 14 updates covering more than 75 vulnerabilities, two of which were publicly disclosed prior to today’s patch release.

The Microsoft updates affect all supported Windows operating systems, as well as all supported versions of Internet Explorer/Edge, Office, Sharepoint and Exchange Server.

All of the critical vulnerabilities from Microsoft are in browsers and browser-related technologies, according to a post from security firm Qualys.

“It is recommended that these be prioritized for workstation-type devices,” wrote Jimmy Graham, director of product management at Qualys. “Any system that accesses the Internet via a browser should be patched.”

The Microsoft vulnerabilities that were publicly disclosed prior to today involve Microsoft Exchange Server 2010 through 2016 editions (CVE-2018-0940) and ASP.NET Core 2.0 (CVE-2018-0808), said Chris Goettl at Ivanti. Microsoft says it has no evidence that attackers have exploited either flaw in active attacks online.

But Goettl says public disclosure means enough information was released publicly for an attacker to get a jump start or potentially to have access to proof-of-concept code making an exploit more likely. “Both of the disclosed vulnerabilities are rated as Important, so not as severe, but the risk of exploit is higher due to the disclosure,” Goettl said.

Critical Security Fixes from Adobe, Microsoft

Adobe has released updates to fix dozens of vulnerabilities in its Acrobat, Reader and Flash Player software. Separately, Microsoft today issued patches to plug 48 security holes in Windows and other Microsoft products. If you use Windows or Adobe products, it’s time once again to get your patches on.

brokenwindowsMore than two dozen of the vulnerabilities fixed in today’s Windows patch bundle address “critical” flaws that can be exploited by malware or miscreants to assume complete, remote control over a vulnerable PC with little or no help from the user.

Security firm Qualys recommends that top priority for patching should go to a vulnerability in the Windows Search service, noting that this is the third recent Patch Tuesday to feature a vulnerability in this service.

Qualys’ Jimmy Graham observes that many of the vulnerabilities in this month’s release involve the Windows Scripting Engine, which can impact both browsers and Microsoft Office, and should be considered for prioritizing for workstation-type systems.

According to Microsoft, none of flaws in August’s Patch Tuesday are being actively exploited in the wild, although Bleeping Computer notes that three of the bugs were publicly detailed before today’s patch release.

Case in point: This month’s patch batch from Microsoft does not address the recently-detailed SMBLoris flaw, a vulnerability in all versions of Windows that can be used to remotely freeze up vulnerable systems or cause them to crash. Continue reading →
