Libreswan CVE-2013-2052 DNS TXT Record Buffer Overflow Vulnerability

Libreswan is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input.

Attackers can exploit this issue to execute arbitrary code within the context of the affected application or cause the application to crash, resulting in denial-of-service conditions.

Libreswan 3.0 and 3.1 are vulnerable.
