ikiwiki 3.20161229 released with [[!toggle text="these changes"]]
[[!toggleable text="""
* Security: force CGI::FormBuilder->field to scalar context where
necessary, avoiding unintended function argument injection
analogous to [[!debcve CVE-2014-1572]]. In ikiwiki this could be used to
forge commit metadata, but thankfully nothing more serious.
([[!debcve CVE-2016-9646]])
* Security: try revert operations in a temporary working tree before
approving them. Previously, automatic rename detection could result in
a revert writing outside the wiki srcdir or altering a file that the
reverting user should not be able to alter, an authorization bypass.
([[!debcve CVE-2016-10026]] represents the original vulnerability.)
The incomplete fix released in 3.20161219 was not effective for git
versions prior to 2.8.0rc0.
([[!debcve CVE-2016-9645]] represents that incomplete solution.)
* Add CVE references for CVE-2016-10026
* Add automated test for using the CGI with git, including
CVE-2016-10026
- Build-depend on libipc-run-perl for better build-time test coverage
* Add missing ikiwiki.setup for the manual test for CVE-2016-10026
* git: don't issue a warning if the rcsinfo CGI parameter is undefined
* git: do not fail to commit changes with a recent git version
and an anonymous committer"""]]
