Fixed In Version: expat 2.4.5
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences (for example, from start tag names) to the XML processing application on top of expat can lead to arbitrary code execution. This issue is dependent on how invalid UTF-8 is handled inside the XML processor.

Description Avinash Hanwate 2022-02-21 05:24:36 UTC
