[Secure-testing-team] Bug#775727: sensible-utils: [PATCH] sensible-pager doesn't check for recursion like sensible-editor does

[Marcel Partap]

Package: sensible-utils
Version: 0.0.9
Severity: important
Tags: security patch

This triggers in rare cases where PAGER=sensible-pager - then it effectively
acts as a forkbomb.
Remedy (adapted from sensible-editor):

+ # Prevent recursive loops, where these values are set to this script
+ p="$(which sensible-pager)"
+ [ "$(which $PAGER || true)" = "$p" ] && PAGER=
