    Multiple vulnerabilities were found in opensc, a set of libraries and     utilities to access smart cards, which could lead to application crash,     information leak, or PIN bypass.

    CVE-2021-34193

        Multiple stack overflow vulnerabilities were discovered in OpenSC         smart card middleware via crafted responses to APDUs.

    CVE-2021-42778

        A heap double free issue was found in sc_pkcs15_free_tokeninfo().

    CVE-2021-42779

        A heap use after free issue was found in sc_file_valid().

    CVE-2021-42780

        A use after return issue was found in the insert_pin() function,         which could potentially crash programs using the library.

    CVE-2021-42781

        Multiple heap buffer overflow issues were found in         pkcs15-oberthur.c, which could potentially crash programs using the         library.

    CVE-2021-42782

        Multiple buffer overflow issues were found in various places, which         could potentially crash programs using the library.

    CVE-2023-2977

        A buffer overrun vulnerability was found in pkcs15's         cardos_have_verifyrc_package().  When supplying a smart card package         with malformed ASN.1 context, an attacker can trigger a crash or         information leak via heap-based buffer out-of-bound read.

    CVE-2023-5992

         Alicja Karion discovered that the code handling the PKCS#1.5          encryption padding removal was not implemented in side-channel          resistant way, which can lead to decryption of previously captured          RSA ciphertexts and forging of signatures based on the timing data          (Marvin attack).

    CVE-2023-40660

        Deepanjan Pal discovered a potential PIN bypass with empty PIN.
        When the token/card was plugged into the computer and authenticated         from one process, it could be used to provide cryptographic         operations from different process when the empty, zero-length PIN         was provided.

    CVE-2023-40661

        Multiple memory vulnerabilities were found by dynamic analyzers in         pkcs15-init.

    CVE-2024-1454

        A memory use after free issue was found in AuthentIC driver when         updating token info.

    CVE-2024-8443

        An heap buffer overflow issue was found in OpenPGP driver during key         generation.

    CVE-2024-45615

        Matteo Marini discovered multiple uses of uninitialized values in         libopensc and pkcs15init.

    CVE-2024-45616

        Matteo Marini discovered multiple uses of uninitialized values after         incorrect check or usage of APDU response values in libopensc.

    CVE-2024-45617

        Matteo Marini discovered multiple uses of uninitialized values after         incorrect or missing checking return values of functions in         libopensc.

    CVE-2024-45618

        Matteo Marini discovered multiple uses of uninitialized values after         incorrect or missing checking return values of functions in         pkcs15init.

    CVE-2024-45619

        Matteo Marini discovered multiple incorrect handling of length of         buffers or files in libopensc, which could result in application         crash or information leak.  When buffers are partially filled with         data, uninitialized parts of the buffer may be incorrectly accessed.

    CVE-2024-45620

        Matteo Marini discovered multiple incorrect handling of length of         buffers or files in pkcs15init, which could result in application         crash or information leak.  When buffers are partially filled with         data, uninitialized parts of the buffer may be incorrectly accessed.

    For Debian 11 bullseye, these problems have been fixed in version     0.21.0-1+deb11u1.

    We recommend that you upgrade your opensc packages.
