Microsoft today issued security updates to plug some 80 security holes in various flavors of its Windows operating systems and related software. The software giant assigned a “critical” rating to almost a quarter of those vulnerabilities, meaning they could be used by malware or miscreants to hijack vulnerable systems with little or no interaction on the part of the user.
Two of the bugs quashed in this month’s patch batch (CVE-2019-1214 and CVE-2019-1215) involve vulnerabilities in all supported versions of Windows that have already been exploited in the wild. Both are known as “privilege escalation” flaws in that they allow an attacker to assume the all-powerful administrator status on a targeted system. Exploits for these types of weaknesses are often deployed along with other attacks that don’t require administrative rights.
September also marks the fourth time this year Microsoft has fixed critical bugs in its Remote Desktop Protocol (RDP) feature, with four critical flaws being patched in the service. According to security vendor Qualys, these Remote Desktop flaws were discovered in a code review by Microsoft, and in order to exploit them an attacker would have to trick a user into connecting to a malicious or hacked RDP server.
Microsoft also fixed another critical vulnerability in the way Windows handles link files ending in “.lnk” that could be used to launch malware on a vulnerable syste ..
