A flaw was found in expat. Passing one or more namespace separator characters in the “xmlns[:prefix]” attribute values made expat send malformed tag names to the XML processor on top of expat. This issue causes arbitrary code execution depending on how unexpected cases are handled inside the XML processor.

Mitigation

There is no known mitigation other than restricting applications using the expat library from processing untrusted XML content. Please update the affected packages as soon as possible.
