Description Eugene Teo (Security Response) 2010-05-25 04:31:27 UTC

Description of problem:
We should be checking for the ownership of the file for which flags are being set, rather than just for write access.

Red Hat would like to thank Dan Rosenberg for responsibly reporting this issue.

Statement:

Red Hat is aware of this issue and is tracking it via the following bug:
https://bugzilla.redhat.com/CVE-2010-1641.

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include
support for the GFS2 file system.

A future kernel update in Red Hat Enterprise Linux 5 will address this issue.
