CVE-2011-1080  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade RHEL:6 kernel-doc to version 0:2.6.32-71.29.1.el6 or higher.
This issue was patched in RHSA-2011:0498.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The do_replace function in net/bridge/netfilter/ebtables.c in the Linux kernel before 2.6.39 does not ensure that a certain name field ends with a '\0' character, which allows local users to obtain potentially sensitive information from kernel stack memory by leveraging the CAP_NET_ADMIN capability to replace a table, and then reading a modprobe command line.
