Description Lubomir Kundrak 2006-10-17 05:18:34 EDT
Description of problem:

Mutt contains two race condition issues in its temporary file handling system.
First one is caused by O_EXCL problem on NFS volumes (CVE-2006-5297). Second one
is lack of check of file mode and ownership of temporary file after file
creation attempt (CVE-2006-5298).                                              

Version-Release number of selected component (if applicable):

All mutt versions prior to 1.5.12
mutt 1.4.1-12.el4

How reproducible:

Racing with mutt wile it attempts to create and use a temporary file.

This [1] is how was the issue fixed in mutt's CVS, following the discussion and
patch proposal in mutt-dev mailing list [2]. Eventually review.

Comment 1 Lubomir Kundrak 2006-10-17 05:30:22 EDT
Also Affects RHEL 2.1, RHEL 3, RHEL 4, and FC 1 to FC 5.
Comment 2 Miroslav Lichvar 2006-10-24 12:03:36 EDT
The O_EXCL on NFS issue fixed in FC5, FC6, devel.

The second issue is not actually a bug as explained later in the mailing list.
