1492212: CVE-2017-1000253 kernel: load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary
A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable (PIE), the loader could allow part of that application's data segment to map over the memory area reserved for its stack, potentially resulting in memory corruption. An unprivileged local user with access to SUID (or otherwise privileged) PIE binary could use this flaw to escalate their privileges on the system.

Statement

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 and 6. This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7 prior to kernel version 3.10.0-693, that is Red Hat Enterprise Linux 7.4 GA kernel version. Kernel versions after 3.10.0-693 contain the fix and are thus not vulnerable.

This issue affects the Linux kernel-rt packages prior to the kernel version 3.10.0-693.rt56.617 (Red Hat Enteprise Linux for Realtime) and 3.10.0-693.2.1.rt56.585.el6rt (Red Hat Enterprise MRG 2). The latest Linux kernel-rt packages as shipped with Red Hat Enterprise Linux for Realtime and Red Hat Enterprise MRG 2 are not vulnerable.

Future Linux kernel updates for the respective releases will address this issue.
