CVE-2024-33602: nscd: netgroup cache assumes NSS callback uses in-buffer strings
First published: Thu Apr 25 2024(Updated: )
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.
