Highlights of Patch Watch Issue 6

 

  1. Microsoft fixed 112 Security bugs in the November patch Tuesday.

  • 24 CVEs are associated with Remote Code Execution hence patching these would be optimum.
  • Microsoft has also changed its security advisories by limiting the disclosing information for each bug.
  • Of these, 17 are critical, 93 are as important, and two are low in severity.
  • Among the bugs patched, zero-day bug - CVE-2020-17087, an actively exploitable vulnerability with PE capabilities.
  • CVE-2020-17087 exists in Windows Kernel Cryptography Driver which constitutes a locally accessible attack surface.
  • When CVE-2020-15999 (type of memory-corruption vulnerability) and CVE-2020-17087 are linked together would allow an attacker to break out of Google Chrome’s sandbox. 
  1. We analyzed 525 vulnerabilities and found that –

  • 17 CVEs have known exploits
  • 1 CVE is associated with Sea turtle APT group
  • 1 CVE has ties with Satan Ransomware
  • 508 are yet to be weaponized
  • Exploitable vulnerabilities are correlated with RCE, DoS, WEB APP, Local, PE, and others.

According to a study by the University of Maryland, a cyber attack occurs once every 39 seconds (2,244 times per day). Cyber Hygiene is the only arsenal that can be employed by security teams to combat threat actors who mount bold and daring attacks on organizations every day.

Organizations today working with massive data sets are undoubtedly challenged with securely managing those data. So, urge patching and prevent your organization from falling victim to an attack.

Happy Patching
