Bugzilla: 1028148: CVE-2013-2929 kernel: exec/ptrace: get_dumpable() incorrect tests


A flaw was found in the way the get_dumpable() function return value was interpreted in the ptrace subsystem of the Linux kernel. When 'fs.suid_dumpable' was set to 2, a local, unprivileged local user could use this flaw to bypass intended ptrace restrictions and obtain potentially sensitive information.
