If the glibc packages are compromised, the Linux system cannot function correctly without the above-mentioned libraries.
The security updates include following fixes for the given vulnerabilities.
CVE-2017-16997
glibc: This CVE number is allotted to an incorrect handling of RPATH in elf/dl-load.c, which can be used to execute code, loaded from arbitrary libraries.
CVE-2018-6485
glibc: This vulnerability results from an Integer overflow in posix_memalign in memalign functions.
CVE-2018-11236
glibc: This issue is caused by an Integer overflow in stdlib/canonicalize.c on 32-bit architectures. It leads to stack-based buffer overflow.
CVE-2018-11237
glibc: This problem arises from a Buffer overflow in __mempcpy_avx512_no_vzeroupper.
