CVE-2011-2534
개요
CVE.org에서
Buffer overflow in the clusterip_proc_write function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel before 2.6.39 might allow local users to cause a denial of service or have unspecified other impact via a crafted write operation, related to string data that lacks a terminating '\0' character.
내용
This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not have support for ipt_CLUSTERIP. This has been addressed in Red Hat Enterprise Linux 5, 6, and Red Hat Enterprise MRG via http://rhn.redhat.com/errata/RHSA-2011-0833.html, http://rhn.redhat.com/errata/RHSA-2011-0498.html, and http://rhn.redhat.com/errata/RHSA-2011-0500.html.
CVSS (Common Vulnerability Scoring System) 점수 세부 사항
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).
