Ispravljene su dvije ranjivosti kod jezgre operacijskog sustava Red Hat Enterprise Linux 6 koje su zloćudni korisnici mogli iskoristiti za DoS (eng. Denial of Service, DoS) napad i otkrivanje osjetljivih informacija.
| Paket: | Linux kernel 2.6.x |
| Operacijski sustavi: | Red Hat Enterprise Linux 6 |
| Kritičnost: | 4.9 |
| Problem: | cjelobrojno prepisivanje, pogreška u programskoj funkciji |
| Iskorištavanje: | lokalno |
| Posljedica: | otkrivanje osjetljivih informacija, uskraćivanje usluga (DoS) |
| Rješenje: | programska zakrpa proizvođača |
| CVE: | CVE-2011-1078, CVE-2012-2383 |
| Izvorni ID preporuke: | RHSA-2012:1156-01 |
| Izvor: | Red Hat |
| Problem: | |
| Pronađena je greška u funkciji "sco_sock_getsockopt_old()" te cjelobrojno prepisivanje u funkciji "i915_gem_execbuffer2()". |
|
| Posljedica: | |
| Lokalni napadač koristeći navedene ranjivosti može srušiti sustav i pregledavati povjerljive podatke. |
|
| Rješenje: | |
| Kao rješenje problema sigurnosti preporuča se žurna nadogradnja jezgre operacijskog sustava. |

Red Hat Security Advisory
Synopsis: Moderate: kernel security and bug fix update
Advisory ID: RHSA-2012:1156-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1156.html
Issue date: 2012-08-14
CVE Names: CVE-2011-1078 CVE-2012-2383
=====================================================================
1. Summary:
Updated kernel packages that fix two security issues and several bugs are
now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64
3. Description:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* An integer overflow flaw was found in the i915_gem_execbuffer2() function
in the Intel i915 driver in the Linux kernel. A local, unprivileged user
could use this flaw to cause a denial of service. This issue only affected
32-bit systems. (CVE-2012-2383, Moderate)
* A missing initialization flaw was found in the sco_sock_getsockopt_old()
function in the Linux kernel's Bluetooth implementation. A local,
unprivileged user could use this flaw to cause an information leak.
(CVE-2011-1078, Low)
Red Hat would like to thank Vasiliy Kulikov of Openwall for reporting the
CVE-2011-1078 issue.
This update also fixes several bugs. Documentation for these changes will
be available shortly from the Technical Notes document linked to in the
References section.
Users should upgrade to these updated packages, which contain backported
patches to correct these issues, and fix the bugs noted in the Technical
Notes. The system must be rebooted for this update to take effect.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
To install kernel packages manually, use "rpm -ivh [package]". Do not
use "rpm -Uvh" as that will remove the running kernel binaries from
your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
5. Bugs fixed (http://bugzilla.redhat.com/):
681259 - CVE-2011-1078 kernel: bt sco_conninfo infoleak
824176 - CVE-2012-2383 kernel: drm/i915: integer overflow in
i915_gem_execbuffer2()
842429 - VLAN configured on top of a bonded interface (active-backup) does not
failover [rhel-6.3.z]
