DESCRIPTION:
Janek Vind has discovered two vulnerabilities in Calibre, which can
be exploited by malicious users to disclose potentially sensitive
information and by malicious people to conduct cross-site scripting
attacks.

1) Input passed via the URL is not properly verified before being
used to display files in
site-packages/calibre/library/server/content.py and can be exploited
to disclose the contents of arbitrary files via directory traversal
attacks and a trailing dot in the filename.

2) Input passed to the "query" parameter in browse/search is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Successful exploitation of these vulnerabilities requires the
"Content Server" to be enabled (disabled by default).

The vulnerabilities are confirmed in version 0.7.34. Other versions
may also be affected.

SOLUTION:
Restrict access to trusted users only. Filter malicious characters
and character sequences in a proxy.
