CVE’s, Patches, and Security Updates - oh my!
The recent security updates and patch releases for Microsoft, Cisco, and Adobe were particularly critical for February. Staying on top of these Common Vulnerabilities and Exposures (CVEs) will keep the proverbial kinks out of your company’s armor, allowing you to maintain a secure working environment. Below we’ve detailed a few of the most critical updates this month for Microsoft, Adobe, and Cisco. Let’s Review.
Last week’s Microsoft Patch Tuesday release likely resulted in a busy and wild week for server administrators and other remediation administrators alike.
12 of the 99 vulnerability patches released were considered critical.
One of the patches (CVE-2020-0674) fixes a particularly nasty vulnerability in Internet Explorer, which Microsoft had released an Out-Of-Band advisory for last month.The workarounds are suggested in the advisory, now that the vulnerability has been fixed.
Another one of the patches, considered a stand-alone, that was issued to address a bug in the Unified Extensible Firmware Interface (UEFI) boot manager, has now been removed. The update was apparently causing widespread problems in the user community with failed installations and profile corruption among other issues. Administrators and home users should be advised to ensure that servers and PCs have recent, successful backups prior to applying these patches.

Adobe also released patches this month to address vulnerabilities found in,
These addressed 17 flaws, including one critical flaw in Flash Player. Adobe is still on track to (finally) retire Flash Player later this year. Chrome and Firefox will update Flash Player using Auto-Update, even though it is now disabled by default in both browsers.
Cisco released several disclosures earlier this month, including critical issues with Cisco Discovery Protocol (CDP) which could result in denial-of-service and remote code execution. They have since released software updates that address these vulnerabilities. Customers are recommended to update software and disable CDP where CDP functionality is not required.
