Denial Of Service (DoS)

openswan is vulnerable to denial of service DoS. The vulnerability exists as a use-after-free flaw was found in the way Openswan's pluto IKE daemon used cryptographic helpers. A remote, authenticated attacker could send a specially-crafted IKE packet that would crash the pluto daemon. This issue...

CVE-2019-12312

In Libreswan 3.27 an assertion failure can lead to a pluto IKE daemon restart. An attacker can trigger a NULL pointer dereference by initiating an IKEv2 IKESAINIT exchange, followed by a bogus INFORMATIONAL exchange instead of the normallly expected IKEAUTH exchange. This affects...
