    CVE: CVE-2020-29361,

    Multiple integer overflows have been discovered in the array allocations in
    the p11-kit library and the p11-kit list command, where overflow checks are
    missing before calling realloc or calloc (CVE-2020-29361).
    
    A heap-based buffer over-read has been discovered in the RPC protocol used by
    the p11-kit server/remote commands and the client library. When the remote
    entity supplies a byte array through a serialized PKCS#11 function call, the
    receiving entity may allow the reading of up to 4 bytes of memory past the
    heap allocation (CVE-2020-29362).
    
    A heap-based buffer overflow has been discovered in the RPC protocol used by
    p11-kit server/remote commands and the client library. When the remote entity
    supplies a serialized byte array in a CK_ATTRIBUTE, the receiving entity may
    not allocate sufficient length for the buffer to store the deserialized value
    (CVE-2020-29363).
