Security Bulletin: IBM MQ Appliance is affected by multiple libxml2 vulnerabilities

Description

## Summary IBM MQ Appliance has addressed multiple libxml2 vulnerabilities. ## Vulnerability Details **CVEID: **[CVE-2015-8035](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-8035>) **DESCRIPTION: **libxml2 is vulnerable to a denial of service, caused by the failure to properly detect compression errors by the xz_decomp function. By using specially-crafted XML data, a local attacker could exploit this vulnerability to cause the process to hang. CVSS Base score: 4 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/107845](<https://exchange.xforce.ibmcloud.com/vulnerabilities/107845>) for the current score. CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) **CVEID: **[CVE-2017-15412](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-15412>) **DESCRIPTION: **Google Chrome could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free in libXML. By persuading a victim to visit a specially-crafted website, a remote attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service. CVSS Base score: 6.3 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/136046](<https://exchange.xforce.ibmcloud.com/vulnerabilities/136046>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L) **CVEID: **[CVE-2017-18258](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-18258>) **DESCRIPTION: **libxml2 is vulnerable to a denial of service, caused by a flaw in the xz_head function in xzlib.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause a denial of service condition. CVSS Base score: 5.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/141432](<https://exchange.xforce.ibmcloud.com/vulnerabilities/141432>) for the current score.
