Vigil@nce: Solaris, denial of service via sendfilev()

August 2008 by Vigil@nce


A local attacker can use maliciously the sendfilev() function, in order to create a denial of service on the computer.

Gravity: 1/4

Consequences: denial of service of computer

Provenance: user shell

Means of attack: no proof of concept, no attack

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

Identifier: VIGILANCE-VUL-8008

- OpenSolaris [confidential versions]
- Sun Solaris [confidential versions]


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.
