What is Libreswan?

Libreswan patches four CVEs on two lines, two of them credited to Claude and Ada Logics.

Libreswan is an IPsec VPN implementation for Linux and the BSDs. On October 5 it released 5.4.1 and 5.3.3 together: 5.4.1 fixes three CVEs (null-pointer crashes on unexpected EAP and empty PKCS7 payloads, and a use-after-free on EOF in IKE over TCP), and 5.3.3 fixes the same three plus a FIPS certificate-leak denial of service. v5.4 in August remains the latest feature release, adding ML-KEM 768 post-quantum key exchange via RFC 9370.

What is Manticore Search?

Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.

Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

Libreswan vs Manticore Search: editorial side-by-side

L
Libreswan
DEVOPS
5.0

Libreswan patches four CVEs on two lines, two of them credited to Claude and Ada Logics.

◆ Current state

Libreswan is an IPsec VPN implementation for Linux and the BSDs. On October 5 it released 5.4.1 and 5.3.3 together: 5.4.1 fixes three CVEs (null-pointer crashes on unexpected EAP and empty PKCS7 payloads, and a use-after-free on EOF in IKE over TCP), and 5.3.3 fixes the same three plus a FIPS certificate-leak denial of service. v5.4 in August remains the latest feature release, adding ML-KEM 768 post-quantum key exchange via RFC 9370.

◆ Where it's heading

Security response dominates the release history: 5.3.1, 5.3.2, 5.3.3 and 5.4.1 are all CVE releases, with 5.4 the one feature release among them. Recent CVEs credit AI-assisted audits, so the find rate may stay high while that tooling runs over the codebase.

◆ Prediction

Expect further point releases on both the 5.3 and 5.4 lines while 5.3 is still maintained. The entries do not show when a 5.5 feature release is due.

M5.0

Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.

◆ Current state

Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.

◆ Where it's heading

The 31.x line is in steady correctness work, with several tags a week and each fixing one edge case in real-time tables, backups or query paths. No feature work has shown up in the feed since 31.0 began.

◆ Prediction

Expect more single-fix 31.0.x tags; the entries give no sign of when the next feature release lands.
