Description OSIDB Bzimport 2024-09-02 18:36:46 UTC

The reported issues are part of the libopensc library, which makes them
accessible from OpenSC tools, PKCS#11 module, minidriver, or CTK.
The attack requires a crafted USB device or smart card that would present
the system with specially crafted responses to the APDUs, so they are
considered high complexity and low severity.

When buffers are partially filled with data, uninitialized parts of the
buffer can be incorrectly accessed.
The uninitialized variables were reflected in the following functions:

- insert_cert
- asn1_encode_path
- gemsafe_get_cert_len
- setcos_generate_key
- sc_hsm_determine_free_id
- coolkey_rsa_op
