Doc Text:	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.	Story Points:	---

Description TEJ RATHI 2023-04-26 06:34:48 UTC

The libreswan flaw CVE-2023-30570 (bug 2187165) was addressed in Red Hat Enterprise Linux 8 via erratum RHSA-2023:2122 and in Red Hat Enterprise Linux 9 via erratum RHSA-2023:2120, released on May 04, 2023:

https://access.redhat.com/errata/RHSA-2023:2122
https://access.redhat.com/errata/RHSA-2023:2120

However, the fix for this issue was not included in the libreswan updates released as part of Red Hat Enterprise Linux 8.8 GA erratum (RHBA-2023:2865) and Red Hat Enterprise Linux 9.2 GA erratum (RHBA-2023:2355), causing a security regression of previously released fix. A new CVE-ID CVE-2023-2295 was assigned for this security regression.

Note that this issue and CVE-ID is specific to the libreswan packages as shipped with Red Hat Enterprise Linux and is not applicable to any upstream libreswan version or libreswan packages of any other vendor that are not directly based on Red Hat Enterprise Linux packages.
