Synopsis :

A web browser on the remote host is affected by multiple
vulnerabilities.

Description :

The installed version of SeaMonkey is affected by various security
issues :

- Several stability bugs leading to crashes which, in
some cases, show traces of memory corruption

- Several file input focus stealing vulnerabilities
that could result in uploading of arbitrary files
provided their full path and file names are known.

- Several issues that allow scripts from page content
to escape from their sandboxed context and/or run
with chrome privileges, resulting in privilege
escalation, XSS, and/or remote code execution.

- A directory traversal vulnerability via the
'chrome:' URI.

- A vulnerability involving 'designMode' frames that
may result in web browsing history and forward
navigation stealing.

- An information disclosure issue in the BMP
decoder.

- Mis-handling of locally-saved plain text files.

- Possible disclosure of sensitive URL parameters,
such as session tokens, via the .href property of
stylesheet DOM nodes reflecting the final URI of
the stylesheet after following any 302 redirects.

- A heap buffer overflow that can be triggered
when viewing an email with an external MIME
body.

- Multiple cross-site scripting vulnerabilities
related to character encoding.
