From 78b79876761b86653df89c48a7010b5cbd41a84a Mon Sep 17 00:00:00 2001 From: Vasiliy Kulikov Date: Tue, 15 Mar 2011 13:36:05 +0100 Subject: [PATCH] netfilter: ip_tables: fix infoleak to userspace Structures ipt_replace, compat_ipt_replace, and xt_get_revision are copied from userspace. Fields of these structs that are zero-terminated strings are not checked. When they are used as argument to a format string containing "%s" in request_module(), some sensitive information is leaked to userspace via argument of spawned modprobe process. The first and the third bugs were introduced before the git epoch; the second was introduced in 2722971c (v2.6.17-rc1). To trigger the bug one should have CAP_NET_ADMIN.
