Summary
Red Hat Security Advisory: libreswan security update
Notes
Topic
An update for libreswan is now available for Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Libreswan is an implementation of IPsec and IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. 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)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: libreswan security update
Notes
Topic
An update for libreswan is available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Libreswan is an implementation of IPsec and IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks such as virtual private network (VPN).
Security Fix(es):
* libreswan: Missing PreSharedKey for connection can cause crash (CVE-2024-2357)

Summary
Red Hat Security Advisory: libreswan security and bug fix update
Notes
Topic
An update for libreswan is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Libreswan is an implementation of IPsec and IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks such as virtual private network (VPN).
Security Fix(es):
* libreswan: Missing PreSharedKey for connection can cause crash (CVE-2024-2357)
Bug Fix(es):
* Connection cannot be established when IPv6 IP SAN is used (JIRA:RHEL-33350)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
