Rocky Linux 8 : libreswan (RLSA-2022:0199)

high Nessus Plugin ID 184698

Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-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, libreswan-debuginfo and / or libreswan-debugsource packages.
