The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to buffer overflow in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. A remote attacker can cause the server to share the DH1024 private key among multiple clients and perform attack on TLS.
