The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0039 advisory.

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

    CVE-2023-2295:
    A vulnerability was found in the libreswan library. This security issue occurs when an IKEv1 Aggressive     Mode packet is received with only unacceptable crypto algorithms, and the response packet is not sent with     a zero responder SPI. When a subsequent packet is received where the sender reuses the libreswan responder     SPI as its own initiator SPI, the pluto daemon state machine crashes. No remote code execution is     possible. This CVE exists because of a CVE-2023-30570 security regression for libreswan package in Red Hat     Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2.

    CVE-2023-30570:
    pluto in Libreswan before 4.11 allows a denial of service (responder SPI mishandling and daemon crash) via     unauthenticated IKEv1 Aggressive Mode packets. The earliest affected version is 3.28.

    CVE-2023-38710:
    An issue was discovered in Libreswan before 4.12. When an IKEv2 Child SA REKEY packet contains an invalid     IPsec protocol ID number of 0 or 1, an error notify INVALID_SPI is sent back. The notify payload's     protocol ID is copied from the incoming packet, but the code that verifies outgoing packets fails an     assertion that the protocol ID must be ESP (2) or AH(3) and causes the pluto daemon to crash and restart.
    NOTE: the earliest affected version is 3.20.

    CVE-2023-38711:
    An issue was discovered in Libreswan before 4.12. When an IKEv1 Quick Mode connection configured with     ID_IPV4_ADDR or ID_IPV6_ADDR receives an IDcr payload with ID_FQDN, a NULL pointer dereference causes a     crash and restart of the pluto daemon. NOTE: the earliest affected version is 4.6.

    CVE-2023-38712:
    An issue was discovered in Libreswan 3.x and 4.x before 4.12. When an IKEv1 ISAKMP SA Informational     Exchange packet contains a Delete/Notify payload followed by further Notifies that act on the ISAKMP SA,     such as a duplicated Delete/Notify message, a NULL pointer dereference on the deleted state causes the     pluto daemon to crash and restart.
