What is NSD?

NSD's 4.15 line is being shaped by outside researchers' bug reports.

NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.

What is Scalingo?

Scalingo opens its Application Firewall to every app and adds CLI commands for it.

Scalingo is a European PaaS that keeps runtimes close to upstream. On November 9 its Application Firewall became available for all applications, letting any app restrict public HTTP and HTTPS access to allowed IPv4 ranges, and CLI 1.52.0 added commands to list, add and remove those rules plus an organizations command. Earlier in the month it patched every stack image for a Brotli decoder CVE and rebuilt nginx against zlib 1.4.

NSD vs Scalingo: editorial side-by-side

N
NSD
DEVOPS
5.0

NSD's 4.15 line is being shaped by outside researchers' bug reports.

◆ Current state

NLnet Labs shipped two NSD releases in October. 4.15.3 fixed four CVEs in the simdzone zone-file parser that only crafted zone files can trigger, a risk mainly for multi-tenant setups where third parties feed zone data. 4.15.4 adds a report-channel EDNS option, a catalog-group-pattern setting that limits which patterns catalog member zones may use, and the UNECE and ISO record types, alongside a long list of fixes credited to researchers at Palo Alto Networks and Tsinghua University.

◆ Where it's heading

Most of the 4.15 cycle is reactive: four security or bug-fix releases since August, with outside researchers finding parser overflows, crashes on malformed catalog zones and IXFR edge cases. Features still arrive, and at least one, catalog-group-pattern, was suggested by a researcher who also reported bugs. Catalog zones and zone-file parsing are where the attention is concentrated.

◆ Prediction

Expect more fixes in catalog zone and zone-file parsing as outside fuzzing continues, likely in another 4.15 patch. The entries give no sign of a 4.16 feature release.

5.0

Scalingo opens its Application Firewall to every app and adds CLI commands for it.

◆ Current state

Scalingo is a European PaaS that keeps runtimes close to upstream. On November 9 its Application Firewall became available for all applications, letting any app restrict public HTTP and HTTPS access to allowed IPv4 ranges, and CLI 1.52.0 added commands to list, add and remove those rules plus an organizations command. Earlier in the month it patched every stack image for a Brotli decoder CVE and rebuilt nginx against zlib 1.4.

◆ Where it's heading

After October's router incident, the platform is adding security controls at the edge alongside its routine runtime updates. Firewall rules in the CLI suggest they are meant to be scripted, not just set in the dashboard.

◆ Prediction

Expect the firewall to gain more options, IPv6 ranges being the obvious gap, alongside the usual buildpack updates.
