Name of the Vulnerable Software and Affected Versions strongSwan versions prior to 5.5.3

Description The issue is related to the ASN.1 parser in strongSwan, which improperly handles CHOICE types when the x509 plugin is enabled. This allows remote attackers to cause a denial of service, resulting in an infinite loop, by providing a crafted certificate.

Recommendations For versions prior to 5.5.3, update to version 5.5.3 or later to resolve the issue.
