Security Bulletin
Summary
The agent core framework component makes use of expat. 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. The expat XML parser is vulnerable to a denial of service, caused by the failure to use sufficient entropy for hash initialization.
