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-2017-9050
Description: libxml2 is vulnerable to a
heap-based buffer overflow, caused by a buffer over-read flaw in
the xmlDictAddString function in dict.c. By sending a
specially-crafted request, a local attacker could overflow a buffer
and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/126277
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2017-9049
Description: libxml2 is vulnerable to a
heap-based buffer overflow, caused by a buffer over-read flaw in
the xmlDictComputeFastKey function in dict.c. By sending a
specially-crafted request, a local attacker could overflow a buffer
and cause the application to crash.
CVSS Base Score: 5.9

CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2017-9048
Description: libxml2 is vulnerable to a
stack-based buffer overflow, caused by improper bounds checking of
the strlen(buf) size in the xmlSnprintfElementContent function in
valid.c. By sending a specially-crafted request, a local attacker
could overflow a buffer and cause the application to crash.
CVSS Base Score: 5.9

CVEID: CVE-2017-9047
Description: libxml2 is vulnerable to a
stack-based buffer overflow, caused by improper bounds checking by
the xmlSnprintfElementContent function in valid.c. By sending a
specially-crafted request, a local attacker could overflow a buffer
and cause the application to crash.

CVEID: CVE-2016-9318
Description: libxml2 could allow a remote
attacker to obtain sensitive information, caused by failure to
offer a flag directly indicating the status of current document. By
using a specially-crafted document to conduct a XML external entity
(XXE) attack, an attacker could exploit this vulnerability to
obtain sensitive information.
