Description Josh Bressers 2005-05-13 20:42:32 UTC 
+++ This bug was initially created as a clone of Bug #157694 +++

Race condition in the rmtree function in File::Path.pm in Perl before 5.8.4
allows local users to create arbitrary setuid binaries in the tree being
deleted, a different vulnerability than CAN-2004-0452.

"Race condition in the rmtree function in File::Path.pm in Perl before 5.8.4

5.8.4 means FC3 is unaffected because we have perl-5.8.5?  Can someone confirm?
Comment 2 Josh Bressers 2005-05-28 12:41:46 UTC 
Warren,

I just took a look at the latest perl source, this issue has not been fixed by
upstream.  It's proving very hard to do right, which is probably why upstream
hasn't done it yet.

Attachment to fix this security bug is from Ubuntu, but we require help cleaning
it up and testing before issuing a FC3 update.  Apparently this is a difficult
problem to fix, and this is our second attempt doing so. =(

debian's 03_fix_file_path

Why not just use the debian patch? (attached)

Assigning to self.
Comment 6 Petr Rockai 2005-06-16 12:15:19 UTC 
Patched in CVS. Testing requested - if anyone has an exploit or something like 
that, please try out. The testsuite passes exactly like before patching, but 
regression testing is welcome as well.
Comment 7 Petr Rockai 2005-07-28 13:07:41 UTC 
Fixed in FC3 update perl-5.8.5-14.FC3
