Description: Vulnerability in the Java SE component of Oracle Java SE (subcomponent: JavaFX). Supported versions that are affected are Java SE: 7u181, 8u172 and 10.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator).

CWE: CWE-22
Description: It has been discovered that redhat-certification does not properly sanitize paths in rhcertStore.py:__saveResultsFile. A remote attacker could use this flaw to overwrite any file, potentially gaining remote code execution.
Mitigation: If SELinux is enabled it further restricts the set of files an attacker may write to. This prevents some basic attacks that would allow to gain remote code execution, though it is not excluded other means are possible.
CVE-2018-11762 (Moderate severity, published 2018-09-18)
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-119
Description: In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue did not reproduce for that version according to the maintainer or a reliable third-party
Statement: This vulnerability is rated as moderate because it allows a remote attacker to cause a denial of service via a NULL pointer dereference, exploiting this flaw would crash the application, impacting availability but not compromising system integrity.

CVE-2018-18955 (Important severity, published 2018-11-14)
CVSS score: 7.8 (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H)
CWE: CWE-285
Description: A flaw was found in the Linux kernel where map_write() in kernel/user_namespace.c allows privilege escalation as it mishandles nested user namespaces with more than 5 UID or GID ranges. An unprivileged user with CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace. This is possible because a user/group id transformation takes place properly for the namespaced-to-kernel direction but not for the kernel-to-namespaced direction.
Statement: This issue does not affect the Linux kernel versions as shipped with Red Hat Enterprise Linux 5, 6 and 7 because they did not include the commit that introduced this issue.

This issue does not affect Red Hat Enterprise Linux 8 because the fix for this issue has not been included since the Red Hat Enterprise Linux 8 release.
CVE-2018-7755 (Low severity, published 2018-03-07)
CVSS score: 5.9 (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N)
CWE: CWE-200
Description: An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR.

Statement: This issue did not affect the versions of puppet-agent as shipped with Red Hat Satellite 6 as this issue is specific to Windows platform only.
CVE-2018-6144 (Low severity, published 2018-05-28)

CVSS score: 7.5 (CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H)
CWE: CWE-367
Description: A flaw was discovered in the API endpoint behind the 'docker cp' command. The endpoint is vulnerable to a Time Of Check to Time Of Use (TOCTOU) vulnerability in the way it handles symbolic links inside a container. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.
Statement: All versions of docker prior to the fix are vulnerable to this flaw.

For clarity, in the "Affected Packages State" table, we only include OpenShift Container Platform (OCP) versions 3.7 and below because for these versions docker was shipped as part of the release.  For all subsequent versions of OCP until 3.11, docker is installed from the RHEL Extras repository meaning clusters will be vulnerable to the flaw unless an updated docker package has been applied.

Red Hat Fuse provides only the Docker client library and is not affected by this vulnerability.
Mitigation: Stopping a container prior to running "docker cp" removes the TOCTOU vulnerability.

CWE: CWE-787
Description: A heap buffer write overflow, with control over the bytes written, was found in the way regular expressions employing Unicode rules are compiled. An attacker, with the ability to provide a specially crafted regular expression, could crash the perl interpreter, or possibly execute arbitrary code.
Statement: Versions of the perl interpreter older than 5.18 are not vulnerable. As a result, the versions of perl as shipped in Red Hat Enterprise Linux version 7, 6 and 5 are not affected by this vulnerability.
CVE-2018-1052 (Moderate severity, published 2018-02-07)

CWE: CWE-77
Description: It was found that rbd-target-api service provided by ceph-iscsi-cli was running in debug mode. An unauthenticated attacker could use this to remotely execute arbitrary code and escalate privileges.
Statement: This issue affects the versions of ceph-iscsi-cli as shipped with Red Hat Ceph Storage 2 and 3. This flaw does not affect python-werkzeug library. It depends on if application uses python-werkzeug library with debug mode enabled.
Mitigation: To stop werkzeug debug mode started by rbd-target-api which is provided by ceph-iscsi-cli:

1. ~]# systemctl stop rbd-target-api

2. ~]# vi /usr/bin/rbd-target-api

# Start the API server
...
737     app.run(host='0.0.0.0',

739             debug=True,       <==== change this to debug=False
                    use_evalex=False,   <=== add this line to disable debugger code execution
740             use_reloader=False,
741             ssl_context=context)
...

after changes it should be

# Start the API server
...
737     app.run(host='0.0.0.0',
738             port=settings.config.api_port,
739             debug=False,

CWE: CWE-200
Description: A user enumeration vulnerability flaw was found in OpenSSH, though version 7.7. The vulnerability occurs by not delaying bailout for an invalid authenticated user until after the packet containing the request has been fully parsed. The highest threat from this vulnerability is to data confidentiality.
Statement: Red Hat Product Security has rated this issue as having Low severity. An attacker could use this flaw to determine whether given usernames exist or not on the server, but no further information is disclosed and there is no availability or integrity impact. A future update may address this issue.
Mitigation: Configuring your firewall to limit the origin and/or rate of incoming ssh connections (using the netfilter xt_recent module) will limit the impact of this attack, as it requires a new TCP connection for each username tested. This configuration also provides some protection against brute-force attacks on SSH passwords or keys.
