Security Bulletin: IBM Bootable Media Creator (BoMC) is affected by vulnerabilities in the kernel

Summary

IBM Bootable Media Creator (BoMC) has addressed the following vulnerabilities.

Vulnerability Details

CVEID:CVE-2015-2922
**DESCRIPTION:**Linux Kernel, built with the IPv6 networking support(CONFIG_IPV6), is vulnerable to a denial of service, caused by the improper handling of Router Advertisements. A remote attacker from within the local network could exploit this vulnerability to set the hop_limit too low and cause a denial of service.
CVSS Base score: 3.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/102058 for the current score.
CVSS Vector: (AV:A/AC:L/Au:N/C:N/I:N/A:P)

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 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 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/162665 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)
