Bug#442245: CVE-2007-4849 insecure permission storage in JFFS2

[Nico Golde]

Package: linux-2.6
Severity: normal
Tags: security

Hi,
a CVE has been issued against JFFS2 which is included in the
linux kernel.
CVE-2007-4849[0]:
JFFS2, as used on One Laptop Per Child (OLPC) build 542 and possibly other
Linux systems, when POSIX ACL support is enabled, does not properly store
permissions during (1) inode creation or (2) ACL setting, which might allow
local users to access restricted files or directories after a remount of a
filesystem, related to "legacy modes" and an inconsistency between dentry
permissions and inode permissions.

If you fix this issue please include the CVE id in the changelog.

Kind regards
Nico
