Description Josh Bressers 2005-05-27 15:32:03 UTC

Race condition in shtool 2.0.1 and earlier allows local users to
create or modify arbitrary files via a symlink attack on the
.shtool.$$ temporary file.
http://www.zataz.net/adviso/shtool-05252005.txt

openldap contains shtool in its source.

Comment 1 Joe Orton 2005-05-27 15:43:58 UTC

Note that this issue can only be triggered when:

a) rebuilding the PHP source RPM
b) building a third-party PHP module

Proposing for inclusion in U2.

Comment 3 Josh Bressers 2005-05-27 16:58:47 UTC

Yes, we'll just include this in either U2 or our next security update.  No need
to roll new packages just for this.
