Firefox < 0.9.3 Null Character MIME Type Spoofing Arbitrary Code Execution
High Nessus Plugin ID 14197
SynopsisThe remote Windows host contains a web browser that has a code execution vulnerability.
DescriptionThe installed version of Firefox is earlier than 0.9.3. Such versions may allow arbitrary code execution.
The security vulnerability is due to the fact that Firefox stores cached HTML documents with a known file name, and to the fact that it's possible to force Firefox to open cached files as HTML documents by appending a NULL byte after the file name.
A remote attacker may combine these two flaws to execute arbitrary code on the remote host.
SolutionUpgrade to Firefox 0.9.3 or later.
