Summary
IBM Integrated Management Module II (IMM2) for System x, Flex
and BladeCenter Systems has addressed the following vulnerabilities
in libxml2.
Vulnerability Details:
CVEID: CVE-2017-7376
Description: libxml2 is vulnerable to a denial
of service, caused by the incorrect limit used when calculating the
port value in xmlParse3986Port function. An attacker could exploit
this vulnerability to cause a denial of service.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/128276
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-7375
Description: libxml2 could allow a remote
attacker to obtain sensitive information, caused by missing
validation for external entities in xmlParsePEReference. By sending
specially-crafted XML data, an attacker could exploit this
vulnerability to obtain sensitive information or cause a denial of
service.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/128275
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:L)
CVEID: CVE-2017-5969
Description: libxml2 is vulnerable to a denial
of service, caused by a NULL pointer dereference in the xmlSaveDoc
functionality when used in recover mode. By persuading a victim to
open a specially crafted XML document, an attacker could exploit
this vulnerability to cause the application to crash.
CVSS Base Score: 5.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/128274
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-0663
Description: Google Android could allow a
remote attacker to execute arbitrary code on the system, caused by
a flaw in libxml2. By persuading a victim to open a
specially-crafted file, an attacker could exploit this
vulnerability to execute arbitrary code within the context of an
unprivileged process.
CVSS Base Score: 7.8
