Unknown vulnerability in SGI IRIX 6.5 through 6.5.22m allows remote attackers to cause a denial of service via a certain UDP packet.

SGI IRIX before 6.5.21 allows local users to cause a denial of service (kernel panic) via a certain call to the PIOCSWATCH ioctl.

Unknown vulnerability in nsd in SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, allows attackers to cause a denial of service (memory consumption).

The Name Service Daemon (nsd), when running on an NIS master on SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, allows remote attackers to cause a denial of service (crash) via a UDP port scan.

SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, does not follow "-" entries in the /etc/group file, which may cause subsequent group membership entries to be processed inadvertently.
