Description Josh Bressers 2005-05-27 15:28:49 UTC
+++ This bug was initially created as a clone of Bug #158997 +++

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.

php contains shtool in its source.

Comment 1 Josh Bressers 2005-05-27 15:29:27 UTC
This issue should also affect FC4

Comment 2 Joe Orton 2005-05-27 15:46:31 UTC
Note that this issue can only be triggered when:

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

This issue alone is not worth issuing an update for; it can be deferred until
there is a new upstream release or some other more serious issue.

Comment 3 Joe Orton 2005-07-05 15:33:30 UTC
Fixed for FC4 in FEDORA-2005-518.
