Microsoft Patch Tuesday, February 2020 Edition

Microsoft today released updates to plug nearly 100 security holes in various versions of its Windows operating system and related software, including a zero-day vulnerability in Internet Explorer (IE) that is actively being exploited. Also, Adobe has issued a bevy of security updates for its various products, including Flash Player and Adobe Reader/Acrobat.

A dozen of the vulnerabilities Microsoft patched today are rated “critical,” meaning malware or miscreants could exploit them remotely to gain complete control over an affected system with little to no help from the user.

Last month, Microsoft released an advisory warning that attackers were exploiting a previously unknown flaw in IE. That vulnerability, assigned as CVE-2020-0674, has been patched with this month’s release. It could be used to install malware just by getting a user to browse to a malicious or hacked Web site.

Microsoft once again fixed a critical flaw in the way Windows handles shortcut (.lnk) files (CVE-2020-0729) that affects Windows 8 and 10 systems, as well as Windows Server 2008-2012. Allan Liska, intelligence analyst at Recorded Future, says Microsoft considers exploitation of the vulnerability unlikely, but that a similar vulnerability discovered last year, CVE-2019-1280, was being actively exploited by the Astaroth trojan as recently as September.

Another flaw fixed this month in Microsoft Exchange 2010 through 2019 may merit special attention. The bug could allow attackers to exploit the Exchange Server and execute arbitrary code just by sending a specially crafted email. This vulnerability¬†(CVE-2020-0688) is rated “important” rather than “critical,” but Liska says it seems potentially dangerous, as Microsoft identifies this as a vulnerability that is likely to be exploited.

In addition, Redmond addressed a critical issue (CVE-2020-0618) in the way Microsoft SQL Server versions 2012-2016 handle page requests.

After a several-month respite from patches for its Flash Player browser plug-in, Adobe has once again blessed us with a security update for this program (fixes one critical flaw). Thankfully, Chrome and Firefox both now disable Flash by default, and Chrome and IE/Edge auto-update the program when new security updates are available. Adobe is slated to retire Flash Player later this year. Continue reading →
