Details
It was discovered that EDK II incorrectly handled input validation in
MdeModulePkg. A local user could possibly use this issue to cause EDK II to
crash, resulting in a denial of service, obtain sensitive information or
execute arbitrary code. (CVE-2019-11098)
Paul Kehrer discovered that OpenSSL used in EDK II incorrectly handled
certain input lengths in EVP functions. An attacker could possibly use this
issue to cause EDK II to crash, resulting in a denial of service.
