Name of the Vulnerable Software and Affected Versions strongSwan versions prior to 5.1.2 strongSwan versions prior to 5.1.3

Description The issue allows remote attackers to cause a denial of service, resulting in a NULL pointer dereference and IKE daemon crash, via a crafted ID DER ASN1 DN ID payload. Multiple vulnerabilities in the strongSwan package can lead to breaches of confidentiality and integrity of protected information, and can be exploited remotely.
