CVE-2017-1000366 (opens in a new tab)How to fix?
Upgrade RHEL:7 glibc to version 0:2.17-157.el7_3.4 or higher.
This issue was patched in RHSA-2017:1481.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.
