Summary

Multiple vulnerabilities have been identified in Expat that is embedded in the IBM FSM. This bulletin addresses these vulnerabilities.

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
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114435 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
