Vigil@nce: Linux kernel, remote access via dccp_setsockopt_change()
August 2008 by Vigil@nce
A remote attacker can maliciously use "dccp_setsockopt_change" function to generate a "Kernel Panic" and thus generate a denial of service.
Consequences: denial of service of computer
Provenance: internet client
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)

Linux kernel [confidential versions]
DCCP protocol provide a way to gain access to congestion control mechanisms.
The Linux Kernel implements this protocol in net/dccp/ directory.
The "dccp_setsockopt_change" function implemented in proto.c file, can be exploited to generates a "Kernel Panic".
A remote attacker can therefore maliciously use "dccp_setsockopt_change" function to generate a "Kernel Panic" and thus generate a denial of service.
Identifiers: BID-30704, CVE-2008-3276, VIGILANCE-VUL-8036
