Security Bulletin: Linux Kernel as used in IBM QRadar Network Packet Capture is
vulnerable to denial of service (CVE-2019-11477, CVE-2019-11478,
CVE-2019-11479)
Document Information
Modified date: 19 September 2019
UID: ibm11074268
Summary
Linux Kernel as used in IBM QRadar Network Packet Capture is vulnerable to
denial of service
Vulnerability Details
CVEID: CVE-2019-11477
Description: Linux Kernel is vulnerable to a denial of service, caused by an
integer overflow when processing TCP Selective Acknowledgement (SACK)
capabilities. By sending specially-crafted SACKs requests, a remote attacker
could exploit this vulnerability to cause a kernel panic condition.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
162662 for the current score
CVSS Environmental Score: *Undefined
CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CVEID: CVE-2019-11478
Description: Linux Kernel is vulnerable to a denial of service, caused by an
issue with fragmenting the TCP retransmission queue when processing TCP
Selective Acknowledgement (SACK) capabilities. By sending specially-crafted
SACKs requests, a remote attacker could exploit this vulnerability to cause an
excess of system resource usage.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
162664 for the current score
CVSS Environmental Score: *Undefined
CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CVEID: CVE-2019-11479
Description: Linux Kernel is vulnerable to a denial of service, caused by a
flaw when processing minimum segment size (MSS). By sending specially-crafted
MSS traffic, a remote attacker could exploit this vulnerability to cause excess
usage of system resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

Security Bulletin: IBM QRadar Network Packet Capture is vulnerable to Intel
Microarchitectural Data Sampling (MDS) Vulnerabilites (CVE-2018-12126,
CVE-2018-12127, CVE-2018-12130, CVE-2019-11091)
Document Information
Modified date: 19 September 2019
UID: ibm11074266
Summary
A potential security vulnerability in CPUs may allow information disclosure.
Vulnerability Details
CVEID: CVE-2018-12126
Description: Intel Microprocessor could allow a local authenticated attacker to
obtain sensitive information, caused by a Microarchitectural Data Sampling
(MDS) vulnerability that stores buffers on some microprocessors utilizing
speculative execution. An attacker could exploit this vulnerability using a
side-channel attack to obtain data that is being processed in the CPU by other
apps. Note: This is called the Zombieload attack.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

CVSS Environmental Score: *Undefined
CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
CVEID: CVE-2018-12127
Description: Intel Microprocessor could allow a local authenticated attacker to
obtain sensitive information, caused by a Microarchitectural Data Sampling
(MDS) vulnerability that fills buffers on some microprocessors utilizing
speculative execution. An attacker could exploit this vulnerability using a
side-channel attack to obtain data that is being processed in the CPU by other
apps. Note: This is called the Zombieload attack.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
CVEID: CVE-2019-11091
Description: Intel Microprocessor could allow a local authenticated attacker to
obtain sensitive information, caused by a Microarchitectural Data Sampling
Uncacheable Memory (MDSUM) vulnerability that allows uncacheable memory on some
microprocessors utilizing speculative execution. An attacker could exploit this
vulnerability using a side-channel attack to obtain data that is being
processed in the CPU by other apps. Note: This is called the Zombieload attack.
