- CVE-2012-6702: Expat, when used in a parser that has not
 called XML_SetHashSalt or passed it a seed of 0, made it easier for
 context-dependent attackers to defeat cryptographic protection mechanisms
 via vectors involving use of the srand function. (bsc#983215)
- CVE-2016-5300: The XML parser in Expat did not use sufficient entropy
 for hash initialization, which allowed context-dependent attackers to
 cause a denial of service (CPU consumption) via crafted identifiers in
 an XML document. NOTE: this vulnerability exists because of an incomplete
 fix for CVE-2012-0876. (bsc#983216)");
