Description: SGI has reported multiple vulnerabilities in the Name Service Daemon (nsd) in IRIX. 1) It is possible to cause a DoS (Denial of Service) on the nsd service by performing a UDP portscanning on a NIS master. 2) Group entries in "/etc/group" are not ignored even though they have a minus ("-") in front of the name. 3) A specially crafted dynamic table may consume all memory resources. 4) DNS callbacks are not sanitised properly. The vulnerabilities affect all versions of IRIX 6.5 prior to version 6.5.21. Solution: Update to version 6.5.21 or apply patch.
