| CVE-2023-39908 | 1 Yubico | 1 Yubihsm 2 Sdk | 2023-08-22 | N/A | 7.5 HIGH |
| The PKCS11 module of the YubiHSM 2 SDK through 2023.01 does not properly validate the length of specific read operations on object metadata. This may lead to disclosure of uninitialized and previously used memory. | |||||
| CVE-2021-43399 | 1 Yubico | 1 Yubihsm 2 Software Development Kit | 2022-02-25 | 7.8 HIGH | 7.5 HIGH |
| The Yubico YubiHSM YubiHSM2 library 2021.08, included in the yubihsm-shell project, does not properly validate the length of some operations including SSH signing requests, and some data operations received from a YubiHSM 2 device. | |||||
| 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-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-2021-28484 | 2 Fedoraproject, Yubico | 2 Fedora, Yubihsm Connector | 2021-06-04 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the /api/connector endpoint handler in Yubico yubihsm-connector before 3.0.1 (in YubiHSM SDK before 2021.04). The handler did not validate the length of the request, which can lead to a state where yubihsm-connector becomes stuck in a loop waiting for the YubiHSM to send it data, preventing any further operations until the yubihsm-connector is restarted. An attacker can send 0, 1, or 2 bytes to trigger this. | |||||
| CVE-2019-12210 | 1 Yubico | 1 Pam-u2f | 2020-08-24 | 5.5 MEDIUM | 8.1 HIGH |
| In Yubico pam-u2f 1.0.7, when configured with debug and a custom debug log file is set using debug_file, that file descriptor is not closed when a new process is spawned. This leads to the file descriptor being inherited into the child process; the child process can then read from and write to it. This can leak sensitive information and also, if written to, be used to fill the disk or plant misinformation. | |||||
| CVE-2019-9578 | 1 Yubico | 1 Libu2f-host | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| In devs.c in Yubico libu2f-host before 1.1.8, the response to init is misparsed, leaking uninitialized stack memory back to the device. | |||||
| CVE-2019-12209 | 1 Yubico | 1 Pam-u2f | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| Yubico pam-u2f 1.0.7 attempts parsing of the configured authfile (default $HOME/.config/Yubico/u2f_keys) as root (unless openasuser was enabled), and does not properly verify that the path lacks symlinks pointing to other files on the system owned by root. If the debug option is enabled in the PAM configuration, part of the file contents of a symlink target will be logged, possibly revealing sensitive information. | |||||
| CVE-2020-10185 | 1 Yubico | 1 Yubikey One Time Password Validation Server | 2020-03-12 | 6.8 MEDIUM | 8.6 HIGH |
| The sync endpoint in YubiKey Validation Server before 2.40 allows remote attackers to replay an OTP. NOTE: this issue is potentially relevant to persons outside Yubico who operate a self-hosted OTP validation service with a non-default configuration such as an open sync pool; the issue does NOT affect YubiCloud. | |||||
| CVE-2020-10184 | 1 Yubico | 1 Yubikey One Time Password Validation Server | 2020-03-12 | 5.0 MEDIUM | 7.5 HIGH |
| The verify endpoint in YubiKey Validation Server before 2.40 does not check the length of SQL queries, which allows remote attackers to cause a denial of service, aka SQL injection. NOTE: this issue is potentially relevant to persons outside Yubico who operate a self-hosted OTP validation service; the issue does NOT affect YubiCloud. | |||||
| CVE-2018-9275 | 1 Yubico | 1 Yubico Pam | 2018-05-21 | 6.4 MEDIUM | 8.2 HIGH |
| In check_user_token in util.c in the Yubico PAM module (aka pam_yubico) 2.18 through 2.25, successful logins can leak file descriptors to the auth mapping file, which can lead to information disclosure (serial number of a device) and/or DoS (reaching the maximum number of file descriptors). | |||||
