CVE-2013-1957
Linux Kernel < 3.8.6 - Local Filesystem Read-Only Bypass via Mount Namespace
Title source: llmDescription
The clone_mnt function in fs/namespace.c in the Linux kernel before 3.8.6 does not properly restrict changes to the MNT_READONLY flag, which allows local users to bypass an intended read-only property of a filesystem by leveraging a separate mount namespace.
