Package: maildrop
Justification: user security hole
Severity: grave
Tags: security
Hi.
Not sure if this actually a hole or if I just misunderstand
something,... but:
In debian /usr/bin/maildrop ist installed:
-rwxr-sr-x 1 root mail 163k Nov 9 01:11 /usr/bin/maildrop
So I'd expect that the following invocation (as root!!):
# maildrop -d vmail
results in something like the following contents of /tmp/foo:
uid=115(vmail) gid=119(vmail) groups=119(vmail),119(vmail)
when ~vmail/.mailfilter is:
`id`
Right so far?
It does however result in:
uid=115(vmail) gid=0(root) groups=119(vmail),0(root)
which can be quite security critical as it now has root-group
privileges.
Cheers,
Chris.
