Package: exim
Version: 3.36-13
Severity: important
Hi,
this problem MAY be a voluntary decision of the exim coders, I don't
know, but anyway it's disturbing :
if you define an alias in /etc/aliases like for example
myalias: "|/usr/bin/somecommand"
then run newaliases, every time you send an email to 'myalias', the
email message you sent is piped into /usr/bin/somecommand
somecommand is run as the user defined in the 'system_aliases'
directive in exim.conf
but only the primary group for this user is initialized, not the
additionnal groups this user is a member of.
maybe a setgroups() function call is missing somewhere in the code,
or something like that.
you can verify this easily, just define such an alias :
myalias: "|/usr/bin/id -Gn"
the error message you'll receive (normal) will anyway list only
the primary group of the user the command is run as, instead of all
the gorups this user is a member of, as can be seen by
launching the same command from the shell (as the very same user)
hoping this helps
bye
