CVE-2022-29505

Privilege escalation via OpenSSL DLL injection

Published Apr 27, 2022 · Updated Aug 3, 2024

DLL injection in the OpenSSL dependency in LINE for Windows before 7.8 allows local users to gain elevated privileges via a crafted DLL. A build misconfiguration permits unsafe DLL loading, but public records do not identify the executable, search path, or OpenSSL directive involved. Exploitation requires local access and user interaction and results in code running with elevated privileges.
