[Freedombox-pkg-team] Bug#876640: plinth: Insecure crypto settings used for auth-pubtkt

[James Valleroy]

Package: plinth
Version: 0.15.1+ds-1
Severity: grave
Tags: security upstream
Justification: user security hole


Due to issues (now fixed) in libapache2-mod-auth-pubtkt, plinth
v0.15.1 has insecure settings for key generation and signing. This may
allow someone to impersonate a plinth user and gain access to apps
that support SSO.

This issue is fixed upstream, but not released yet:
