This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.(CVE-2024-33599)

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 service to the clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33601)

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 when the
cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33600)

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 cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33602)

The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable.(CVE-2024-2961)");
