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):

In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data.(CVE-2026-24515)

In libexpat before 2.7.4, the doContent function does not properly determine the buffer size bufSize because there is no integer overflow check for tag buffer reallocation.(CVE-2026-25210)
