CVE Number = CVE-2018-11056
A vulnerability in RSA BSAFE Micro Edition Suite and Crypto-C Micro Edition could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system.The vulnerability is due to uncontrolled resource consumption by the affected software when parsing ASN.1 data. An attacker could exploit this vulnerability by sending crafted ASN.1 data to a targeted system. A successful exploit could exhaust memory resources, resulting in a DoS condition.RSA has confirmed the vulnerability and released software updates.
- To exploit this vulnerability, the attacker must send ASN.1 data that submits malicious input to the targeted system, making exploitation more difficult in environments that restrict network access from untrusted sources.
- Administrators are advised to apply the appropriate updates.Administrators are advised to allow only trusted users to have network access.Administrators are advised to run both firewall and antivirus applications to minimize the potential of inbound and outbound threats.Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.Administrators can help protect affected systems from external attacks by using a solid firewall strategy.Administrators are advised to monitor affected systems.
- RSA has released a security advisory at the following link: DSA-2018-128
