| 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. | |||||
| CVE-2020-24388 | 2 Fedoraproject, Yubico | 2 Fedora, Yubihsm-shell | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the _send_secure_msg() function of yubihsm-shell through 2.0.2. The function does not validate the embedded length field of a message received from the device. This could lead to an oversized memcpy() call that will crash the running process. This could be used by an attacker to cause a denial of service. | |||||
| CVE-2021-32489 | 1 Yubico | 1 Yubihsm-shell | 2021-05-19 | 3.5 LOW | 4.4 MEDIUM |
| An issue was discovered in the _send_secure_msg() function of Yubico yubihsm-shell through 2.0.3. The function does not correctly validate the embedded length field of an authenticated message received from the device because response_msg.st.len=8 can be accepted but triggers an integer overflow, which causes CRYPTO_cbc128_decrypt (in OpenSSL) to encounter an undersized buffer and experience a segmentation fault. The yubihsm-shell project is included in the YubiHSM 2 SDK product. | |||||
| CVE-2021-27217 | 1 Yubico | 1 Yubihsm-shell | 2021-03-26 | 3.5 LOW | 4.4 MEDIUM |
| An issue was discovered in the _send_secure_msg() function of Yubico yubihsm-shell through 2.0.3. The function does not correctly validate the embedded length field of an authenticated message received from the device. Out-of-bounds reads performed by aes_remove_padding() can crash the running process, depending on the memory layout. This could be used by an attacker to cause a client-side denial of service. The yubihsm-shell project is included in the YubiHSM 2 SDK product. | |||||
