Its been around a long time, but evolves with the C standard and the linux kernel. It is basically a layer between C and the kernel.
Comment on New Glibc Flaw Grants Attackers Root Access on Major Linux Distros

Noob question: that’s a really old library, right? Has this issue been there for decades before someone found it, or is this vulnerability part of some newer addition to it?

glibc is the library that provides basic functionality for C programs. It provides the bottom level implementation for things like opening files, requesting memory, and other OS-level stuff.
glibc isn’t the only implementation out there. Even on Linux, there are other options, such as muslc.
It gets updated regularly, as the C standard or operating system needs. So while it has been around for a very long time (by software standards anyway) it’s still an active and evolving piece of software. --and one that underpins many critical functions of our systems.
