Description Tavis Ormandy (RETIRED) gentoo-dev 2006-12-30 13:08:46 UTC
The script installed and executed by the openldap ebuild uses /tmp insecurely.

The following line:

mkdir -p /tmp/tmpssl-$$

should be replaced with something like

mkdir /tmp/tmpssl-$$ || exit 1

(or print some error and exit, whichever you prefer).

This could be abused by local attackers to cause all sorts of mischief, such as stealing certificates, overwriting arbitrary files, interfering with certificate data, etc, etc.

This bug is fairly critical.
Comment 1 Jakub Moc (RETIRED) gentoo-dev 2006-12-30 13:30:39 UTC
Why are we using this script anyway? We have ssl-cert.eclass for this; it's as easy as docert openldap and install to the proper place, see mail-mta/postfix, net-misc/stunnel, net-mail/cyrus-imapd, net-im/ejabberd or others for usage.

somebody set this to "B3?", which requires GLSA voting. I dont know any details, but this could be a B1 (local priv escal)? I guess this is gentoo specific? 

Voting: yes
