                   Red Hat Security Advisory

Synopsis:          Important: kernel security and bug fix update
Advisory ID:       RHSA-2014:1997-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1997.html
Issue date:        2014-12-16
CVE Names:         CVE-2012-6657 CVE-2014-3673 CVE-2014-3687
                   CVE-2014-3688 CVE-2014-5471 CVE-2014-5472
                   CVE-2014-6410 CVE-2014-9322
=====================================================================

1. Summary:

Updated kernel packages that fix multiple security issues and several bugs
are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important 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.

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

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:

* A flaw was found in the way the Linux kernel handled GS segment register
base switching when recovering from a #SS (stack segment) fault on an
erroneous return to user space. A local, unprivileged user could use this
flaw to escalate their privileges on the system. (CVE-2014-9322, Important)

* A flaw was found in the way the Linux kernel's SCTP implementation
handled malformed or duplicate Address Configuration Change Chunks
(ASCONF). A remote attacker could use either of these flaws to crash the
system. (CVE-2014-3673, CVE-2014-3687, Important)

* A flaw was found in the way the Linux kernel's SCTP implementation
handled the association's output queue. A remote attacker could send
specially crafted packets that would cause the system to use an excessive
amount of memory, leading to a denial of service. (CVE-2014-3688,
Important)

* A stack overflow flaw caused by infinite recursion was found in the way
the Linux kernel's UDF file system implementation processed indirect ICBs.
An attacker with physical access to the system could use a specially
crafted UDF image to crash the system. (CVE-2014-6410, Low)

* It was found that the Linux kernel's networking implementation did not
correctly handle the setting of the keepalive socket option on raw sockets.
A local user able to create a raw socket could use this flaw to crash the
system. (CVE-2012-6657, Low)

* It was found that the parse_rock_ridge_inode_internal() function of the
Linux kernel's ISOFS implementation did not correctly check relocated
directories when processing Rock Ridge child link (CL) tags. An attacker
with physical access to the system could use a specially crafted ISO image
to crash the system or, potentially, escalate their privileges on the
system. (CVE-2014-5471, CVE-2014-5472, Low)

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

Synopsis:          Moderate: mailx security update
Advisory ID:       RHSA-2014:1999-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1999.html
Issue date:        2014-12-16
CVE Names:         CVE-2004-2771 CVE-2014-7844
=====================================================================

1. Summary:

Updated mailx packages that fix two security issues are now available for
Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security 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 Client (v. 7) - x86_64
Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64
Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
Red Hat Enterprise Linux Workstation (v. 7) - x86_64

3. Description:

The mailx packages contain a mail user agent that is used to manage mail
using scripts.

A flaw was found in the way mailx handled the parsing of email addresses.
A syntactically valid email address could allow a local attacker to cause
mailx to execute arbitrary shell commands through shell meta-characters and
the direct command execution functionality. (CVE-2004-2771, CVE-2014-7844)

Note: Applications using mailx to send email to addresses obtained from
untrusted sources will still remain vulnerable to other attacks if they
accept email addresses which start with "-" (so that they can be confused
with mailx options). To counteract this issue, this update also introduces
the "--" option, which will treat the remaining command line arguments as
email addresses.

All mailx users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
