Description

This security bulletin contains information about 1 security vulnerability.


1) Race condition (CVE-ID: CVE-2006-0039)

The vulnerability allows a local user to access sensitive information or perform a denial of service (DoS) attack.

Race condition in the do_add_counters function in netfilter for Linux kernel 2.6.16 allows local users with CAP_NET_ADMIN capabilities to read kernel memory by triggering the race condition in a way that produces a size value that is inconsistent with allocated memory, which leads to a buffer over-read in IPT_ENTRY_ITERATE.


Remediation

Install update from vendor's website.
