The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot find a matching configured secret. When such a connection is automatically added on startup using the auto= keyword, it can cause repeated crashes leading to a Denial of Service.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0207 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2024-2357:
    The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit     scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot     find a matching configured secret. When such a connection is automatically added on startup using the     auto= keyword, it can cause repeated crashes leading to a Denial of Service.

    CVE-2024-3652:
    The Libreswan Project was notified of an issue causing libreswan to restart when using IKEv1 without     specifying an esp= line. When the peer requests AES-GMAC, libreswan's default proposal handler causes an     assertion failure and crashes and restarts. IKEv2 connections are not affected.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit     scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot     find a matching configured secret. When such a connection is automatically added on startup using the     auto= keyword, it can cause repeated crashes leading to a Denial of Service. (CVE-2024-2357)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2024:10594 advisory.

These services allow you     to build secure tunnels through untrusted networks such as virtual private network (VPN).

    Security Fix(es):

    * libreswan: remote DoS via crafted TS payload with an incorrect selector length (CVE-2023-23009)

    * libreswan: Invalid IKEv1 Quick Mode ID causes restart (CVE-2023-38711)

    * libreswan: Invalid IKEv2 REKEY proposal causes restart (CVE-2023-38710)

    * libreswan: Invalid IKEv1 repeat IKE SA delete causes crash and restart (CVE-2023-38712)

    * libreswan: Missing PreSharedKey for connection can cause crash (CVE-2024-2357)
