nscd netgroup cache corruption vulnerability

CVE-2024-33602

Summary

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.
