Vulnerability Details

Summary

Intel® Manycore Platform Software Stack (MPSS) for Linux and Windows have addressed the following vulnerabilities in Expat.

Vulnerability Details:

CVEID: CVE-2012-6702

Description: Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, could provide weaker than expected security. An attacker could exploit this vulnerability using attack vectors involving use of the srand function to defeat cryptographic protection mechanisms.

CVSS Base Score: 5.9
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/114541&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:N/I:H/A:N)

CVEID: CVE-2016-5300

Description: Expat XML parser is vulnerable to a denial of service, caused by the failure to use sufficient entropy for hash initialization. By using specially-crafted identifiers in an XML document, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/114435&gt; for the current score
CVSS Environmental Score*: Undefined
