Some security implications. + + * make-secnet-sites: Prefix names when writing secnet sites.conf file. + + make-secnet-sites must copy names (vpn, location and site names) from + the input sites file (which is not wholly trusted) to the secnet + config file. Prior to this release, naming a location or site the + same as a secnet predefined name could generate a broken sites.conf + which secnet would reject. (With the existing featureset, + malfunctions other than rejection, eg privilege escalation, are not + possible.) + + make-secnet-sites now adds a prefix to these names when writing + sites.conf. This will not affect configurations which use the + make-secnet-sites-provided `all-sites' key, as is usual. Other + configurations will break unless the references in the static part of + the config are adjusted. + + Previous behaviour can be restored with the --no-conf-key-prefix + option. (Planned future enhancements to secnet are likely to make use + of that option, with untrusted input, dangerously insecure.) + + other changes to make-secnet-sites: + * Fix argument parsing. Fixes a regression affecting -P in 0.5.0, + and also fixes new facilities introduced in 0.5.0. + * Sort the properties on output (and adjust the test case expected + outputs). Tests now pass on (at least) Python 2.7.13, 3.5.3, 3.7.5. + * Delete some unused code. + + secnet: + * Change one idiom to avoid a warning from GCC9. No functional change. + + build system - MAJOR CHANGES: + * Fix out-of-tree builds. (Broken in 0.5.0) + * Replace recursive make with use of the new subdirmk system. + This represents a fairly comprehensive overhaul of the makefiles. + Several bugs (esp. involving dependencies between files in different + directories) are fixed. + * Drop `make check' from `make all'. (Otherwise there is no way + to ask for `all' without `check'.) + * Suppress two unhelpful new compiler warnings from GCC9. + * Release checklist update. + + documentation: + * Creit Mark Wooding properly in CREDITS. + * Include DEVELOPER-CERTIFICATE. + + tests: + * Locations now have different names to sites. + * Somewhat better debugging output from mtest. + * Do not run msgcode-test except with `make fullcheck'. + * Other minor bugfixes and improvments. + * stest: Suppress unhelpful -Wno-unused-result (needed for stretch). + + -- Ian Jackson Fri, 22 Nov 2019 23:13:14 +0000 + +secnet (0.5.0) unstable; urgency=medium + + make-secnet-sites SECURITY FIX: + * Do not blindly trust inputs; instead, check the syntax for sanity. + Previous releases can be induced to run arbitrary code as the user + invoking secnet (which might be root), if a secnet sites.conf is used + that was generated from an untrustworthy sites file. + * The userv invocation mode of make-secnet-sites seems to have been safe + in itself, but it previously allowed hazardous data to be propagated + into the master sites file. This is now prevented too. + + make-secnet-sites overhaul work: + * make-secnet-sites is now in the common subset of Python2 and Python3. + The #! is python3 now, but it works with Python2.7 too. + It will probably *not* work with old versions of Python2. + * We no longer depend on the obsolete `ipaddr' library. We use + `ipaddress' now. And this is onlo a Recommends in the .deb. + * Ad-hoc argument parser been replaced with `argparse'. + There should be no change to existing working invocations. + * Bad address syntax error does not wrongly mention IPv6 scopes. + * Minor refactoring to support forthcoming work. [Mark Wooding] + + other bugfixes, improvements and changes to secnet itself: + * Better logging of why we are sending NAK messages. + * Correctly use the verified copy of the peer remote capabilities + from MSG3. (Bug is not a vulnerability.) [Mark Wooding] + * Significant internal rearrangements and refactorings, to support + forthcoming key management work.

[Mark Wooding] + * Handle IPv4 addresses properly (ie, not foolishly byte-swapped), + when IPv6 is not available.
