Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when parsing invalid PEM-encrypted material in mbedtls_pk_parse_key(), mbedtls_pk_parse_keyfile() and mbedtls_pem_read_buffer() functions. A remote attacker can pass specially crafted data to the application, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
