An update is available for glibc.
This update affects Rocky Linux 9.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
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: Out of bounds write in iconv conversion to ISO-2022-CN-EXT
    (CVE-2024-2961)

  • 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)
