CVE-2013-1873

From: Mathias Krause <minipli@googlemail.com>
Subject: [oss-security] Linux kernel: net - three info leaks in rtnl
Date: Tue, 19 Mar 2013 22:15:30 +0100

I fixed a few more info leaks in linux v3.9-rc3. Unprivileged users
can use the netlink interface to exploit the following issues to
disclose kernel stack memory:

29cd8ae dcbnl: fix various netlink info leaks
http://git.kernel.org/linus/29cd8ae0e1a39e239a3a7b67da1986add1199fc0

84d73cd rtnl: fix info leak on RTM_GETLINK request for VF devices
http://git.kernel.org/linus/84d73cd3fb142bf1298a8c13fd4ca50fd2432372

c085c49 bridge: fix mdb info leaks
http://git.kernel.org/linus/c085c49920b2f900ba716b4ca1c1a55ece9872cc

David Miller did backports for the above issues which are currently
under review and should end up in the next stable and longterm
kernels.

Mathias

Comment 3 Marcus Meissner 2013-03-25 11:57:20 UTC 
CVE-2013-2634

commit 29cd8ae0e1a39e239a3a7b67da1986add1199fc0

net/dcb/dcbnl.c in the Linux kernel before 3.8.4 does not initialize
certain structures, which allows local users to obtain sensitive
information from kernel stack memory via a crafted application.


CVE-2013-2635

commit 84d73cd3fb142bf1298a8c13fd4ca50fd2432372

The rtnl_fill_ifinfo function in net/core/rtnetlink.c in the Linux
kernel before 3.8.4 does not initialize a certain structure member,
which allows local users to obtain sensitive information from kernel
stack memory via a crafted application.



CVE-2013-2636

commit c085c49920b2f900ba716b4ca1c1a55ece9872cc

net/bridge/br_mdb.c in the Linux kernel before 3.8.4 does not
initialize certain structures, which allows local users to obtain
sensitive information from kernel memory via a crafted application.
Comment 4 Marcus Meissner 2013-04-19 16:35:32 UTC 
CVE-2013-2634 and CVE-2013-2635 are in
patches.kernel.org/patch-3.0.69-70


CVE-2013-2636 is not in 3.0.stable yet.

> CVE-2013-2634

> commit 29cd8ae0e1a39e239a3a7b67da1986add1199fc0

dcbnl_ieee_fill changes are not applicable to kernels before 2.6.38-rc1 (introduced by 3e29027a)
dcbnl_cee_fill has been introduced in 5b7f7626 around 3.1-rc1.
This leaves us with dcbnl_getperm_hwaddr hunk introduced by 2f90b865 introduced in 2.6.29-rc1.

pushed to SLE11-SP1-TD. Other TD branches are not affected AFACIS.

[...]
> CVE-2013-2635
> 
> commit 84d73cd3fb142bf1298a8c13fd4ca50fd2432372

The leak has been introduced by ebc08a6f in 2.6.34-rc1 AFAIU. This means none of TD branches are affected.

[...]
> 
> CVE-2013-2636
> 
> commit c085c49920b2f900ba716b4ca1c1a55ece9872cc

The leak has been introduced by ee07c6e7 resp. 37a393bc in 3.8-rc1 AFAICS.
So no SLE branch is affected.
