CVE-2010-1641
Description
From CVE.org
The do_gfs2_set_flags function in fs/gfs2/file.c in the Linux kernel before 2.6.34-git10 does not verify the ownership of a file, which allows local users to bypass intended access restrictions via a SETFLAGS ioctl request.
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.
