CVE-2014-3534

Status Candidate

Overview

arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call.

Red Hat Security Advisory 2014-1023-01

Red Hat Security Advisory 2014-1023-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory. It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process.
