Security Bulletin
Summary
IBM DataPower Gateways has addressed vulnerabilities in processing
certain XML files that could cause a denial of service or obtain sensitive
information.
Vulnerability Details
CVEID: CVE-2016-4448
DESCRIPTION: libxml2 could allow a remote attacker to execute arbitrary
code on the system, caused by a format string error. By using a specially
crafted HTML file that contains malicious format specifiers, a remote
attacker could exploit this vulnerability to execute arbitrary code on
the system or cause the application to crash.
CVSS Base Score: 7.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113523 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2016-4449
DESCRIPTION: libxml2 could allow a remote attacker to obtain sensitive
information, caused by a XML external entity (XXE) error when processing XML
data by the XML parser. A remote attacker could exploit this vulnerability
to obtain sensitive information.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113524 for the
current score

CVEID: CVE-2016-3627
DESCRIPTION: libxml2 is vulnerable to a denial of service, caused by an
error in the xmlStringGetNodeList() function when parsing xml files while
in recover mode. An attacker could exploit this vulnerability to exhaust
the stack and cause a segmentation fault.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111586 for the
current score

CVEID: CVE-2016-3705
DESCRIPTION: libxml2 is vulnerable to a stack-based buffer overflow,
caused by an out-of-bounds read of xmlParserEntityCheck() and
xmlParseAttValueComplex() functions in parser.c. By persuading a victim to
open a specially crafted XML file, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 6.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112885 for the

CVEID: CVE-2016-4447
DESCRIPTION: libxml2 is vulnerable to a denial of service, caused by a
heap-based buffer overflow. By persuading a victim to open a specially
crafted XML file, a remote attacker could overflow a buffer and cause the
application to crash.
