Ability of attacker: expert (4/4)
Confidence: confirmed by the editor (5/5)
Diffusion of the vulnerable configuration: high (3/3)
Creation date: 12/08/2008

DESCRIPTION
Solaris has a "sendfilev" function which is used to send a file
(copy buffer to socket)
It seems that a malicious utilisation of the system call
sendfilev() generates a "system panic" error. For now, there is no
technical information published related to this issue.
An attacker with writing permission on the system can therefore
create a program or a web page using the function "sendfilev"
maliciously in order to create a denial of service.
