In Debian jessie, the mutt source package builds two variants of mutt: mutt and mutt-patched.
The previous package version (1.5.23-3+deb8u2, DLA-2268-1) provided fixes for the issues referenced above, but they were only applied for the mutt-patched package build, not for the (vanilla) mutt package build.
