Subject: bash: builtin read doesn't treat signals properly
To: submit@bugs.debian.org
X-Mailer: bug 3.3.9
Delivered-To: submit@bugs.debian.org

Package: bash
Version: 2.04-9
Severity: normal

The builtin read command erroneously inherits some trap settings.  For
instance, if we start

bash -c 'trap "echo hi" USR1; read foo'

and then send it a USR1, it'll echo hi (first breakage, you must not execute
traps until the foreground command has completed) but keep read running.

Now this particular trap is not one which is normally inheritable, so it
must not be inherited by read and the default behaviour for SIGUSR1 is to
terminate the program.
