"Sun Solaris is prone to a remote denial-of-service vulnerability
because of an error in the 'sockfs' kernel module.
Exploiting this issue allows attackers to cause a panic in a vulnerable
Solaris webserver and the system as a whole, effectively denying service
to legitimate users.
This issue affects Solaris 10 and OpenSolaris based on builds snv_41 or
"This issue only occurs if a system is configured as an HTTP server
utilizing the Solaris Network Cache Accelerator (nca(1)) and has logging
enabled. To determine if NCA is enabled on the system, execute the
$ grep status=enabled /etc/nca/ncakmod.conf
It is recommended to install this patch on affected systems. Please let
me know if you are running a Solaris box with nca(1).
