The p11-glue project reports:

CVE-2020-29363: Out-of-bounds write in p11_rpc_buffer_get_byte_array_value function

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-2020-29362: Out-of-bounds read in p11_rpc_buffer_get_byte_array function

A heap-based buffer over-read has been discovered in the RPC protocol used by thep11-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-2020-29361: Integer overflow when allocating memory for arrays of attributes and object identifiers

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.
