| Description |

Security Fix(es): 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. (CVE-2017-1000253, Important) Bugs fixed (https://bugzilla.redhat.com/): BZ - 1492212 - CVE-2017-1000253 kernel: load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary |
