Summary

expat security update

Details

expat is a stream-oriented XML parser library written in C. expat excels with files too large to fit RAM, and where performance and flexibility are crucial.

Security Fix(es):

libexpat before 2.8.2 lacks handler call depth tracking for calls to XMLGetBuffer, XMLParse, XMLParseBuffer, XMLParserFree, or XML_ParserReset from within handlers in cases of a policy violation. Thus, a use-after-free can occur,(CVE-2026-50219)
