A privilege escalation vulnerability exists in Windows due to improper calculation of LDAP request buffer lengths. An attacker could exploit this vulnerability by sending malicious traffic to a Domain Controller using a specially crafted application.
- CVE-2023-45284Medium
The IsLocal function on Windows incorrectly detects reserved device names in some cases. Reserved names followed by spaces (e.g., "COM1 ") and names "COM" and "LPT" with superscript 1, 2, or 3 are incorrectly reported as local. The fix ensures IsLocal now correctly identifies these.
