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. (CVE-2024-33599) 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. (CVE-2024-33600) 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. (CVE-2024-33601) 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. (CVE-2024-33602)
