DESCRIPTION:
Some vulnerabilities have been reported in strongSwan, which can be
exploited by malicious people to potentially compromise a vulnerable
system.

The vulnerabilities are caused due to insecure usage of the
"snprintf()" function when parsing certificates or identification
payload.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are reported in version 4.3.3 and later prior to
4.3.7 and 4.4.1.

SOLUTION:
Apply patches or update to version 4.3.7 or 4.4.1.
