Summary
IBM Dynamic System Analysis (DSA) Preboot has 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
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 a 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
