Synopsis
The remote CentOS host is missing one or more security updates for libreswan.Description
The remote CentOS Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the libreswan-4.12-1.el9 build changelog.- 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-2023-38710)
- 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-2023-38711)
- 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. (CVE-2023-38712)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
