[$] An effort to secure the Network Time Protocol
The Network Time Protocol (NTP) debuted in 1985; it is a universally used, open specification that is deeply important for all sorts of activities we take for granted. It also, despite a number of efforts, remains stubbornly unsecured. Ruben Nijveld presented work at FOSDEM 2026 to speed adoption of the thus-far largely ignored standard for securing NTP traffic: IETF's RFC-8915 that specifies Network Time Security (NTS) for NTP.
MetaBrainz mourns the loss of Robert Kaye
The MetaBrainz Foundation has announced the unexpected passing of its founder and executive director, Robert Kaye:
Robert's vision and leadership shaped MetaBrainz and left a lasting mark on the music industry and open source movement. His contributions were significant and his loss is deeply felt across our global community.
The Board is actively overseeing a smooth leadership transition and has measures in place to ensure that MetaBrainz continues to operate without interruption. Further updates will be shared in due course.
Security updates for Wednesday
GNU Awk 5.4.0 released
Version 5.4.0 of GNU awk (gawk) has been released. This is a major release with a change in gawk's default regular-expression matcher: it now uses MinRX as the default regular-expression engine.
This matcher is fully POSIX compliant, which the current GNU matchers are not. In particular it follows POSIX rules for finding the longest leftmost submatches. It is also more strict as to regular expression syntax, but primarily in a few corner cases that normal, correct, regular expression usage should not encounter.
Because regular expression matching is such a fundamental part of awk/gawk, the original GNU matchers are still included in gawk. In order to use them, give a value to the GAWK_GNU_MATCHERS environment variable before invoking gawk.
[...] The original GNU matchers will eventually be removed from gawk. So, please take the time to notice and report any issues in the MinRX matcher, so that they can be ironed out sooner rather than later.
See the release announcement for additional changes.
Firefox 148.0 released
Version
148 of Firefox has been released. The most notable change in this
release is the addition of a "Block AI enhancements" option that
allows turning off "new or current AI enhancements in Firefox, or
pop-ups about them
" with a single toggle.
With this release, Firefox now supports the Trusted Types API to help prevent cross-site scripting attacks as well as the Sanitizer API that provides new methods for HTML manipulation. See the release notes for developers for changes that may affect web developers or those who create Firefox add-ons.
