"New Red Hat Single Sign-On 7.3.5 packages are now available for Red
Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Red Hat Single Sign-On 7.3 is a standalone server, based on the
Keycloak project, that provides authentication and standards-based
single sign-on capabilities for web and mobile applications.

This release of Red Hat Single Sign-On 7.3.5 on RHEL 7 serves as a
replacement for Red Hat Single Sign-On 7.3.4, and includes bug fixes
and enhancements, which are documented in the Release Notes document
linked to in the References.

Security Fix(es) :

* keycloak: Service accounts reset password flow not using
placeholder.org domain anymore (CVE-2019-14837)

* undertow: HTTP/2: flood using PING frames results in unbounded
memory growth (CVE-2019-9512)

* undertow: HTTP/2: flood using HEADERS frames results in unbounded
memory growth (CVE-2019-9514)

* undertow: HTTP/2: flood using SETTINGS frames results in unbounded
memory growth (CVE-2019-9515)

* wildfly-core: Incorrect privileges for 'Monitor', 'Auditor' and
'Deployer' user by default (CVE-2019-14838)

* wildfly: wildfly-security-manager: security manager authorization
bypass (CVE-2019-14843)

"The remote Windows host is missing security update 4512501.
It is, therefore, affected by multiple vulnerabilities :

  - An elevation of privilege vulnerability exists when
    Windows improperly handles calls to Advanced Local
    Procedure Call (ALPC). An attacker who successfully
    exploited this vulnerability could run arbitrary code in
    the security context of the local system. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2019-1162)

  - A security feature bypass vulnerability exists when
    Microsoft browsers improperly handle requests of
    different origins. The vulnerability allows Microsoft
    browsers to bypass Same-Origin Policy (SOP)
    restrictions, and to allow requests that should
    otherwise be ignored. An attacker who successfully
    exploited the vulnerability could force the browser to
    send data that would otherwise be restricted.
    (CVE-2019-1192)

  - A remote code execution vulnerability exists in the way
    that the scripting engine handles objects in memory in
    Internet Explorer. The vulnerability could corrupt
    memory in such a way that an attacker could execute
    arbitrary code in the context of the current user. An
    attacker who successfully exploited the vulnerability
    could gain the same user rights as the current user.
    (CVE-2019-1133, CVE-2019-1194)

  - A denial of service vulnerability exists when the
    XmlLite runtime (XmlLite.dll) improperly parses XML
    input. An attacker who successfully exploited this
    vulnerability could cause a denial of service against an
    XML application. A remote unauthenticated attacker could
    exploit this vulnerability by issuing specially crafted
    requests to an XML application. The update addresses the
    vulnerability by correcting how the XmlLite runtime
    parses XML input. (CVE-2019-1187)

  - An elevation of privilege vulnerability exists when
    DirectX improperly handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could run arbitrary code in kernel mode. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2019-1176)

  - An information disclosure vulnerability exists when the
    Windows RDP server improperly discloses the contents of
    its memory. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the system.  (CVE-2019-1224, CVE-2019-1225)

  - A remote code execution vulnerability exists when the
    Windows Jet Database Engine improperly handles objects
    in memory. An attacker who successfully exploited this
    vulnerability could execute arbitrary code on a victim
    system. An attacker could exploit this vulnerability by
    enticing a victim to open a specially crafted file. The
    update addresses the vulnerability by correcting the way
    the Windows Jet Database Engine handles objects in
    memory. (CVE-2019-1146, CVE-2019-1147, CVE-2019-1155,
    CVE-2019-1156, CVE-2019-1157)

  - A denial of service vulnerability exists in the HTTP/2
    protocol stack (HTTP.sys) when HTTP.sys improperly
    parses specially crafted HTTP/2 requests. An attacker
    who successfully exploited the vulnerability could
    create a denial of service condition, causing the target
    system to become unresponsive.  (CVE-2019-9511,
    CVE-2019-9512, CVE-2019-9513, CVE-2019-9514,
    CVE-2019-9518)

  - <h1>Executive Summary</h1> Microsoft is aware of the
    Bluetooth BR/EDR (basic rate/enhanced data rate, known
    as &quot;Bluetooth Classic&quot;) key negotiation
    vulnerability that exists at the hardware specification
    level of any BR/EDR Bluetooth device. An attacker could
    potentially be able to negotiate the offered key length
    down to 1 byte of entropy, from a maximum of 16 bytes.
    (CVE-2019-9506)

  - A denial of service vulnerability exists in Remote
    Desktop Protocol (RDP) when an attacker connects to the
    target system using RDP and sends specially crafted

    vulnerability could cause the RDP service on the target
    system to stop responding.  (CVE-2019-1223)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2019-1227)

  - A remote code execution vulnerability exists in
    Microsoft Windows that could allow remote code execution

    crafted application. The update addresses the
    vulnerability by correcting how the Windows Graphics
    Component handles objects in memory. (CVE-2019-1078)

  - An elevation of privilege vulnerability exists in the
    way that the wcmsvc.dll handles objects in memory. An

    (CVE-2019-1180, CVE-2019-1186)

  - A remote code execution vulnerability exists in the way
    that the Chakra scripting engine handles objects in
    memory in Microsoft Edge. The vulnerability could
    corrupt memory in such a way that an attacker could

    user. An attacker who successfully exploited the
    vulnerability could gain the same user rights as the
    current user.  (CVE-2019-1131, CVE-2019-1139,

    way that the ssdpsrv.dll handles objects in memory. An
    attacker who successfully exploited the vulnerability
    could execute code with elevated permissions.
    (CVE-2019-1178)

  - A remote code execution vulnerability exists when the
    Windows font library improperly handles specially
    crafted embedded fonts. An attacker who successfully
    exploited the vulnerability could take control of the
    affected system. An attacker could then install
    programs; view, change, or delete data; or create new
    accounts with full user rights.  (CVE-2019-1144,
    CVE-2019-1145, CVE-2019-1149, CVE-2019-1150,
    CVE-2019-1151, CVE-2019-1152)

  - A security feature bypass exists when Windows

    inject code into a CAB file without invalidating the
    file's signature.  (CVE-2019-1163)

  - An elevation of privilege vulnerability exists when the
    Windows kernel fails to properly handle objects in
    memory. An attacker who successfully exploited this

  - A remote code execution vulnerability exists in Remote
    Desktop Services formerly known as Terminal Services
    when an unauthenticated attacker connects to the target
    system using RDP and sends specially crafted requests.
    This vulnerability is pre-authentication and requires no
