An issue was discovered in the _asn1_decode_simple_ber function in decoding.c in GNU Libtasn1 before 4.13. Unlimited recursion in the BER decoder leads to stack exhaustion and DoS.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
