Package(s):

kernel

CVE #(s):

CVE-2006-2451

Created:

July 7, 2006

Updated:

July 26, 2006

Description:

The Linux kernel, versions 2.6.13 through 2.6.17.3, has a privilege escalation vulnerability that is related to the handling of core dumps. Local users can create a program that can core dump to a directory that the user does not have permission to write to. This can be exploited for the use of a disk consumption denial of service attack, or the unauthorized gaining of root privileges.

As I understand it, this bug affects 2.6.13 and up, and only is an issue in 2.6.9 because RHEL backported the feature in which the problem occurs. Can someone confirm this?

Your understanding is correct - the bug was introduced in 2.6.13. The original wording of this entry was incorrect - fixing it now.
