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.
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
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.
