Debian DSA-4309-1 : strongswan - security update

Google's OSS-Fuzz revealed an exploitable bug in the gmp plugin caused by the patch that fixes CVE-2018-16151 and CVE-2018-16152 DSA-4305-1. An attacker could trigger it using crafted certificates with RSA keys with very small moduli. Verifying signatures with such keys would cause an integer...
