Description Michael Orlitzky gentoo-dev 2017-08-31 01:42:49 UTC
The executables installed to /usr/bin by net-im/jabberd2 are owned by the "jabber" user:

  -rwxr-x---   1 jabber    jabber    9.5K 2017-08-30 21:34 jabberd
  -rwxr-x---   1 jabber    jabber    192K 2017-08-30 21:34 jabberd2-c2s
  -rwxr-x---   1 jabber    jabber    160K 2017-08-30 21:34 jabberd2-router
  -rwxr-x---   1 jabber    jabber    180K 2017-08-30 21:34 jabberd2-s2s
  -rwxr-x---   1 jabber    jabber    180K 2017-08-30 21:34 jabberd2-sm

Those are in root's PATH, and could conceivably be run as root during debugging or experimentation. If that ever happens, it's trivial for the "jabber" user to gain root; instead, those should likely all be root:root, or maybe root:jabber if you want to leave them mode 750.

Is this a Gentoo specific issue? it may be good to report upstream about this.

The ebuild does,

  fowners jabber:jabber /usr/bin/{jabberd,router,sm,c2s,s2s}

so I doubt it's an upstream issue.
Comment 3 Pacho Ramos gentoo-dev 2017-11-09 13:27:27 UTC
Either ones takes care of deeply reviewing the ebuild and init files (due to other opened bugs affecting them) or this should be treecleaned (there is also a pending security issue revbump in other bug)
