- [RHSA-2010:0792-01] Important: kernel security update



[RHSA-2010:0793-01] Important: glibc security update

=====================================================================
Red Hat Security Advisory

Synopsis: Important: glibc security update
Advisory ID: RHSA-2010:0793-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0793.html
Issue date: 2010-10-25
CVE Names: CVE-2010-3856
=====================================================================

1. Summary:

Updated glibc packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system cannot
function properly.

It was discovered that the glibc dynamic linker/loader did not perform
sufficient safety checks when loading dynamic shared objects (DSOs) to
provide callbacks for its auditing API during the execution of
privileged programs. A local attacker could use this flaw to escalate
their privileges via a carefully-chosen system DSO library containing
unsafe constructors. (CVE-2010-3856)

Red Hat would like to thank Ben Hawkes and Tavis Ormandy for reporting this
issue.

All users should upgrade to these updated packages, which contain a
backported patch to correct this issue.

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
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

645672 - CVE-2010-3856 glibc: ld.so arbitrary DSO loading via LD_AUDIT in setuid/setgid programs

[RHSA-2010:0792-01] Important: kernel security update

=====================================================================
Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2010:0792-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0792.html
Issue date: 2010-10-25
CVE Names: CVE-2010-3904
=====================================================================

1. Summary:

Updated kernel packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issue:

* The rds_page_copy_user() function in the Linux kernel Reliable Datagram
Sockets (RDS) protocol implementation was missing sanity checks. A local,
unprivileged user could use this flaw to escalate their privileges.
(CVE-2010-3904, Important)

Red Hat would like to thank Dan Rosenberg of Virtual Security Research for
reporting this issue.

Users should upgrade to these updated packages, which contain a backported
patch to correct this issue. 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
http://kbase.redhat.com/faq/docs/DOC-11259

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/):

642896 - CVE-2010-3904 RDS sockets local privilege escalation
