CVE-2010-0008

Description

From CVE.org

The sctp_rcv_ootb function in the SCTP implementation in the Linux kernel before 2.6.23 allows remote attackers to cause a denial of service (infinite loop) via (1) an Out Of The Blue (OOTB) chunk or (2) a chunk of zero length.

Statement

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not include support for SCTP. It did not affect the version of Linux kernel as shipped with Red Hat Enterprise MRG as it has already had the fix to this issue.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

CWE-770

Availability

Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)

When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
