LIN5-20468 : Security Advisory - linux - CVE-2014-9710

Created: May 31, 2015    Updated: Dec 19, 2017
Resolved Date: Jun 22, 2015
Found In Version: 5.0.1.26
Fix Version: 5.0.1.28
Severity: Standard
Applicable for: Wind River Linux 5
Component/s: Kernel

Description

The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
