CVE-2018-20340 log

Severity High
Remote No
Type Arbitrary code execution
Yubico library libu2f-host prior to version 1.1.7 contains an unchecked buffer, which could allow a buffer overflow. Libu2f-host is a library that implements the host party of the U2F protocol. This issue can allow an attacker with a custom made malicious USB device masquerading as a security key, and physical access to a computer where PAM U2F or an application with libu2f-host integrated, to potentially execute arbitrary code on that computer. Users of the YubiKey PAM U2F Tool are the most impacted since the arbitrary code could execute with elevated privileges.
