Remote attackers can decrypt IPSEC tunnel ciphertext data by leveraging a Bleichenbacher RSA padding oracle. Cause a Bleichenbacher oracle attack. Successful exploit this vulnerability can impact IPSec tunnel security. (Vulnerability ID: HWPSIRT-2017-10055)This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2017-17305.There are two  DoS vulnerabilities in the IPSEC IKEv1 implementations of Huawei Firewall products.  Due to improper handling of the malformed messages, an attacker may sent crafted packets to the affected device to exploit these vulnerabilities. Successful exploit these two vulnerabilities could lead to device deny of service. (Vulnerability ID: HWPSIRT-2017-10147 and HWPSIRT-2017-10148)The two vulnerabilities have been assigned two Common Vulnerabilities and Exposures (CVE) IDs: CVE-2017-17311 and CVE-2017-17312.Huawei has released software updates to fix these vulnerabilities.
