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: stack-based buffer overflow in netgroup cache (CVE-2024-33599)

  • glibc: null pointer dereferences after failed netgroup cache insertion
    (CVE-2024-33600)

  • glibc: netgroup cache may terminate daemon on memory allocation failure
    (CVE-2024-33601)

  • glibc: netgroup cache assumes NSS callback uses in-buffer strings
    (CVE-2024-33602)
