Summary

Vulnerabilities in glibc affect the IBM MQ Appliance. IBM MQ Appliance has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2015-8778 DESCRIPTION: GNU C Library (glibc) could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in hcreate and hcreate_r. An attacker could exploit this vulnerability to trigger an out-of-bound memory access and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/111086&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2015-8779 DESCRIPTION: GNU C Library (glibc) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the catopen function. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

CVEID: CVE-2014-9761 DESCRIPTION: GNU C Library (glibc) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the nan function. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
