29 Nov 2022 — OP-TEE Trusted OS is the secure side implementation of OP-TEE project, a Trusted Execution Environment. Versions prior to 3.19.0, contain an Improper Validation of Array Index vulnerability. The function `cleanup_shm_refs()` is called by both `entry_invoke_command()` and `entry_open_session()`. The commands `OPTEE_MSG_CMD_OPEN_SESSION` and `OPTEE_MSG_CMD_INVOKE_COMMAND` can be executed from the normal world via an OP-TEE SMC. This function is not validating the `num_params` argument, which is only limited t... • https://github.com/OP-TEE/optee_os/blob/c2d449482de098f1c894b94f338440e5a327813d/core/tee/entry_std.c#L257 • CWE-129: Improper Validation of Array Index •

13 Feb 2017 — The rsa_verify_hash_ex function in rsa_verify_hash.c in LibTomCrypt, as used in OP-TEE before 2.2.0, does not validate that the message length is equal to the ASN.1 encoded data length, which makes it easier for remote attackers to forge RSA signatures or public certificates by leveraging a Bleichenbacher signature forgery attack. La función rsa_verify_hash_ex en rsa_verify_hash.c en LibTomCrypt, como se utiliza en OP-TEE en versiones anteriores a 2.2.0, no valida que la longitud del mensaje es igual a la l... • https://bugzilla.redhat.com/show_bug.cgi?id=1370955 • CWE-20: Improper Input Validation •
