CVE-2020-24387 2 Fedoraproject, Yubico 2 Fedora, Yubihsm-shell 2021-07-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the yh_create_session() function of yubihsm-shell through 2.0.2. The function does not explicitly check the returned session id from the device. An invalid session id would lead to out-of-bounds read and write operations in the session array. This could be used by an attacker to cause a denial of service attack.
