A stack overflow vulnerability was found in _nss_dns_getnetbyname_r. On systems with nsswitch configured to include "networks: dns" with a privileged or network-facing service that would attempt to resolve user-provided network names, an attacker could provide an excessively long network name, resulting in stack corruption and code execution.
