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: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary libraries (CVE-2017-16997)
glibc: Integer overflow in posix_memalign in memalign functions (CVE-2018-6485)
glibc: Integer overflow in stdlib/canonicalize.c on 32-bit architectures leading to stack-based buffer overflow (CVE-2018-11236)
glibc: Buffer overflow in __mempcpy_avx512_no_vzeroupper (CVE-2018-11237)
