Oracle Linux 8 : libreswan (ELSA-2022-0199)

high Nessus Plugin ID 156875

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 8 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2022-0199 advisory.

- Libreswan 4.2 through 4.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted IKEv1 packet because pluto/ikev1.c wrongly expects that a state object exists. This is fixed in 4.6. (CVE-2022-23094)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libreswan package.
