Security Bulletin
Summary
IBM QRadar Network Security is affected by Linux kernel vulnerabilities
Vulnerability Details
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/
162665 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/

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/
