CVE-2017-5130 (Important severity, published 2017-10-16)
CVSS score: 8.8 (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
Description: A heap overflow flaw was found in the libxml2 library. An application compiled with libxml2 using the vulnerable debug-only function xmlMemoryStrdup could be used by an attacker to crash the application or execute arbitrary code with the permission of the user running the application.
Statement: This issue does not affect the libxml library shipped with Red Hat Enterprise Linux because the affected code xmlMemoryStrdup() is a debug-only function that should never be called in production builds. The only exception is xmllint when invoked with --maxmem. The same issue applies to the other two affected functions namely xmlMallocLoc and xmlReallocLoc.

CVE-2017-7526 (Moderate severity, published 2017-06-28)
CVSS score: 6.1 (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N)
CWE: CWE-200
Description: libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.
Statement: This side-channel attack requires that the attacker can run arbitrary software on the hardware where the private RSA key is used. Allowing execute access to a box with private keys should be considered as an unsafe security practice, anyway.  Thus in practice there are easier ways to access the private keys than to mount this side-channel attack. However, on boxes with virtual machines this attack may be used by one VM to steal private keys from another VM.
CVE-2017-8779 (Important severity, published 2017-05-02)
CVSS score: 7.5 (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-400
Description: It was found that due to the way rpcbind uses libtirpc (libntirpc), a memory leak can occur when parsing specially crafted XDR messages. An attacker sending thousands of messages to rpcbind could cause its memory usage to grow without bound, eventually causing it to be terminated by the OOM killer.
Statement: In the default system configuration, with the sysctl variable vm.overcommit_memory set to either 0 (the default) or 1, an attack would take a not-insignificant amount of time to exhaust the system's memory. If vm.overcommit_memory is set to a value of 2, the time required to exhaust system memory is sufficiently reduced. It was further noticed that, a 32-bit system would have its memory exhausted faster than a 64-bit system.
Mitigation: rpcbind should be protected by iptables so that only trusted hosts that require access can reach it (eg, nfs clients).  Applying per-IP rate limits in iptables will also significantly limit the impact of this attack.  The default iptables rules in the system-config-firewall or firewalld package deny all remote access to rpcbind.

If you elect to run your system with overcommit turned off, daemons should have memory limits enforced by the init system to ensure stability.  With systemd, use directives such as LimitAS in unit files.  With upstart, place ulimit commands in /etc/sysconfig/$daemon.
CVE-2017-3135 (Moderate severity, published 2017-02-07)
CVSS score: 7.5 (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
Description: A denial of service flaw was found in the way BIND handled query responses when both DNS64 and RPZ were used. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure or a null pointer dereference via a specially crafted DNS response.
Mitigation: While it is possible to avoid the condition by removing either DNS64 or RPZ from the configuration, or by carefully restricting the contents of the policy zone, for an affected configuration the most practical and safest course of action is to upgrade to a version of BIND without this vulnerability.

CWE: CWE-362
Description: A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system.
Statement: This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5.

This issue does affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 6, 7 and Red Hat Enterprise MRG 2. As this issue is rated as Important, it has been scheduled to be fixed in future updates for the respective releases.
Mitigation: The  n_hdlc kernel module will be automatically loaded when an application  attempts to use the HDLC line discipline from userspace.  This module  can be prevented from being loaded by using the system-wide modprobe  rules. The following command, run as root, will prevent accidental or  intentional loading of the module.  Red Hat Product Security believe  this method is a robust method to prevent accidental loading of the  module, even by privileged users.

​# echo "install n_hdlc /bin/true" >> /etc/modprobe.d/disable-n_hdlc.conf

The  system will need to be restarted if the n_hdlc modules are already  loaded.  In most circumstances, the n_hdlc kernel modules will be unable to be unloaded if in use and while any current process using this line  discipline is required.

Exploiting this flaw does not require Microgate or SyncLink hardware to be in use.

CVE-2017-11600 (Moderate severity, published 2017-07-10)
CVSS score: 5.5 (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-125
Description: The xfrm_migrate() function in the net/xfrm/xfrm_policy.c file in the Linux kernel built with CONFIG_XFRM_MIGRATE does not verify if the dir parameter is less than XFRM_POLICY_MAX. This allows a local attacker to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact by sending a XFRM_MSG_MIGRATE netlink message. This flaw is present in the Linux kernel since an introduction of XFRM_MSG_MIGRATE in 2.6.21-rc1, up to 4.13-rc3.
Statement: This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5, 6 as the code with the flaw is not present in the products listed or is not exploitable.

This issue affects the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 7 and Red Hat Enterprise MRG 2. Future kernel updates for these products may address this issue.
