This vulnerability affects all Linux distributions running versions of glibc older than 2.18, and exploits a buffer overflow in the _nss_hostname_digits_dots() function. GHOST is a vulnerability that was announced on January 27th 2015, which affects the glibc library on Linux systems.
If I use the following command, it works. clangd: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by. clangd: /lib64/libc.so.6: version GLIBC_2.18' not found (required by. opt is the standard place to install third-party applications and libraries but you can use any path away from the system paths. If you change LD_LIBRARY_PATH don't export it for the whole system because all the binaries unmodified by patchelf will segfault.

Or you can use patchelf to update the binary's rpath (you can combine this with the previous pathelf command) patchelf -set-rpath /opt/glibc-2.18/lib:/usr/lib64 program_you_are_running Then to run a binary you need to use patchelf to update its interpreter patchelf -set-interpreter /opt/glibc-2.18/lib/ld-linux-x86-64.so.2 program_you_are_runningĪnd you need to enable it to find the new glibc library, either by export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/glibc-2.18/lib Note this must only be done for the application only. You can build the version of glibc you require elsewhere on your server and add it to LD_LIBRARY_PATH for the application.
If it's absolutely necessary to run this application, the official RHEL approach would be to containerize, but you would still need to provide a working glibc, which wouldn't be possible with stock CentOS 7.

CentOS shows the base version as installed and is patched to keep up with changes and it could just be a case of fixing the version that is being looked for in the code as a quick fix, but if the application is being actively developed you need to let the developers know or fork it for yourself if you can.Īn up to date glibc on CentOS 7 should be 2.17-196.el7_4.2 If it is needed, Containerise
Firstly check the python application as it could be out of date and is probably misreading the glibc version.
