Descriptions
An issue was discovered in libexpat before 2.6.4. There is a crash within the XML_ResumeParser function because XML_StopParser can stop/suspend an unstarted parser.
A security issue was found in Expat (libexpat). A crash can be triggered in the XML_ResumeParser function due to XML_StopParser's ability to stop or suspend an unstarted parser, which can lead to a denial of service.
It was discovered that Expat did not properly handle its internal state when attempting to resume an unstarted parser. An attacker could use this issue to cause a denial of service.
