ikiwiki 3.20190228 released with [[!toggle text="these changes"]]

|
* aggregate: Use LWPx::ParanoidAgent if available.
|
|
Previously blogspam, openid and pinger used this module if available,
|
|
but aggregate did not. This prevents server-side request forgery or
|
|
local file disclosure, and mitigates denial of service when slow
|
|
"tarpit" URLs are accessed.
|
|
([[!debcve CVE-2019-9187]])
|
|
* blogspam, openid, pinger: Use a HTTP proxy if configured, even if
|
|
LWPx::ParanoidAgent is installed.
|
|
Previously, only aggregate would obey proxy configuration. If a proxy
|
|
is used, the proxy (not ikiwiki) is responsible for preventing attacks
|
|
like CVE-2019-9187.
|
|
* aggregate, blogspam, openid, pinger: Do not access non-http, non-https
|
|
URLs.
|
|
Previously, these plugins would have allowed non-HTTP-based requests if
|
|
LWPx::ParanoidAgent was not installed. Preventing file URIs avoids local
|
|
file disclosure, and preventing other rarely-used URI schemes like
|
|
gopher mitigates request forgery attacks.
|
|
* aggregate, openid, pinger: Document LWPx::ParanoidAgent as strongly
|
|
recommended.
|
|
These plugins can request attacker-controlled URLs in some site
|
|
configurations.
|
|
* blogspam: Document LWPx::ParanoidAgent as desirable.
|
|
This plugin doesn't request attacker-controlled URLs, so it's
|
|
non-critical here.
|
|
* blogspam, openid, pinger: Consistently use cookiejar if configured.
|
|
Previously, these plugins would only obey this configuration if
|
|
LWPx::ParanoidAgent was not installed, but this appears to have been
|
|
unintended.
|
|
* po: Always filter .po files.
|
|
The po plugin in previous ikiwiki releases made the second and
|
|
subsequent filter call per (page, destpage) pair into a no-op,
|
|
apparently in an attempt to prevent *recursive* filtering (which as
|
|
far as we can tell can't happen anyway), with the undesired effect
|
|
of interpreting the raw .po file as page content (e.g. Markdown)
|
|
if it was inlined into the same page twice, which is apparently
|
|
something that tails.org does. Simplify this by deleting the code
|
|
that prevented repeated filtering. Thanks, intrigeri
