Summary
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)

High 8.1
nscd: Stack-based buffer overflow in netgroup cache
nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted by client requests then a subsequent client request for netgroup data may result in a stack-based buffer overflow. This flaw was introd…

High 7.4
nscd: netgroup cache assumes NSS callback uses in-buffer strings
nscd: netgroup cache assumes NSS callback uses in-buffer strings The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. The flaw was introduced in glibc 2.15 when the c…

The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to …

High 7.3
nscd: netgroup cache may terminate daemon on memory allocation failure
nscd: netgroup cache may terminate daemon on memory allocation failure The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or xrealloc and these functions may terminate the process due to a memory allocation failure resulting in a denial of ser…

Medium 5.9
nscd: Null pointer crashes after notfound response
nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 whe…
