Irix 6.4, 6.5, 6.52 fcagent daemon subject to DoS Attack

IRIX's fcagent daemon is vulnerable to a Denial of Service attack.

IRIX's (versions 6.4, 6.5 and 6.5.2) fcagent daemon is an RPC based
daemon that services requests about status or configuration of a
FibreVault enclosure (a very fast fiber optics installation of Disks).
Fcagent is vulnerable to a remote Denial of Service attack that could
cause the FibreVault to stop responding, making the IRIX's Disk array

By sending a specific RPC packet to the fcagent daemon, the FibreVault
configuration and status monitor can be made inoperable. This causes all
the disks inside the FibreVault to stop responding, sometimes resulting
in a system halt.

A patch for the fcagent daemon exists and SGI advises its customers to
upgrade to IRIX 6.5.2.

upgrading to IRIX 6.5.2 can be found at:
