CVE-2024-33602: nscd: netgroup cache assumes NSS callback uses in-buffer strings
glibc is vulnerable to a denial of service, caused by a memory corruption by the Name Service Cache Daemon's (nscd) netgroup cache when the NSS callback fails to store all strings in the provided buffer. A local attacker could exploit this vulnerability to corrupt memory and cause a denial of service.

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.
— NVD
The buffer-resizing code in addgetnetgrentX assumes that all string pointers point into the supplied buffer.
