RHEL 5 : kernel (RHSA-2017:2801)
high Nessus Plugin ID 194071

Synopsis
The remote Red Hat host is missing a security update for kernel.Description
The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2801 advisory.The kernel packages contain the Linux kernel, the core of any Linux operating system.
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)
Red Hat would like to thank Qualys Research Labs for reporting this issue.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL kernel package based on the guidance in RHSA-2017:2801.See Also
