Summary
The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.
Security Fix(es):
* glibc: Off-by-one buffer overflow/underflow in getcwd() (CVE-2021-3999)
* glibc: Stack-based buffer overflow in svcunix_create via long pathnames (CVE-2022-23218)
* glibc: Stack-based buffer overflow in sunrpc clnt_create via a long pathname (CVE-2022-23219)
