expat: Namespace-separator characters in "xmlns[:prefix]" attribute values can lead to arbitrary code execution

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...

expat: a use-after-free in the doContent function in xmlparse.c

A vulnerability was found in expat. With this flaw, it is possible to create a situation in which parsing is suspended while substituting in an internal entity so that XMLResumeParser directly uses the internalEntityProcessor as its processor. If the subsequent parse includes some unclosed tags,...
