vulnerability (CVE-2014-3603)
Security Bulletin
Summary
IBM Cloud Private is vulnerable to an IBM WebSphere Application Server Liberty
vulnerability
Vulnerability Details
CVEID: CVE-2014-3603
DESCRIPTION: The (1) HttpResource and (2) FileBackedHttpResource
implementations in Shibboleth Identity Provider (IdP) before 2.4.1 and OpenSAML
Java 2.6.2 do not verify that the server hostname matches a domain name in the
subject's Common Name (CN) or subjectAltName field of the X.509 certificate,
which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary
valid certificate.

IBM Cloud Private is vulnerable to IBM WebSphere Application Server Liberty
vulnerabilities
Security Bulletin
Summary
IBM Cloud Private is vulnerable to IBM WebSphere Application Server Liberty
vulnerabilities
Vulnerability Details
CVEID: CVE-2019-9515
DESCRIPTION: Some HTTP/2 implementations are vulnerable to a settings flood,
potentially leading to a denial of service. The attacker sends a stream of
SETTINGS frames to the peer. Since the RFC requires that the peer reply with
one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost
equivalent in behavior to a ping. Depending on how efficiently this data is
queued, this can consume excess CPU, memory, or both.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
165181 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-9518
DESCRIPTION: Some HTTP/2 implementations are vulnerable to a flood of empty
frames, potentially leading to a denial of service. The attacker sends a stream
of frames with an empty payload and without the end-of-stream flag. These
frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends
time processing each frame disproportionate to attack bandwidth. This can
consume excess CPU.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
164904 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-9517
DESCRIPTION: Some HTTP/2 implementations are vulnerable to unconstrained
interal data buffering, potentially leading to a denial of service. The
attacker opens the HTTP/2 window so the peer can send without constraint;
however, they leave the TCP window closed so the peer cannot actually write
(many of) the bytes on the wire. The attacker then sends a stream of requests
for a large response object. Depending on how the servers queue the responses,
this can consume excess memory, CPU, or both.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
165183 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-9512
DESCRIPTION: Some HTTP/2 implementations are vulnerable to ping floods,
potentially leading to a denial of service. The attacker sends continual pings
to an HTTP/2 peer, causing the peer to build an internal queue of responses.
Depending on how efficiently this data is queued, this can consume excess CPU,
memory, or both.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
164903 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-9514
DESCRIPTION: Some HTTP/2 implementations are vulnerable to a reset flood,
potentially leading to a denial of service. The attacker opens a number of
streams and sends an invalid request over each stream that should solicit a
stream of RST_STREAM frames from the peer. Depending on how the peer queues the
RST_STREAM frames, this can consume excess memory, CPU, or both.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
164640 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-9513
DESCRIPTION: Some HTTP/2 implementations are vulnerable to resource loops,
potentially leading to a denial of service. The attacker creates multiple
request streams and continually shuffles the priority of the streams in a way
that causes substantial churn to the priority tree. This can consume excess
CPU.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
164639 for the current score.
