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: buffer overflow in ld.so leading to privilege escalation (CVE-2023-4911)

  • glibc: Stack read overflow in getaddrinfo in no-aaaa mode (CVE-2023-4527)

  • glibc: potential use-after-free in getaddrinfo() (CVE-2023-4806)

  • glibc: potential use-after-free in gaih_inet() (CVE-2023-4813)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
