Date: Tue, 28 Sep 2010 04:21:30 +0000
Package: dropbox
Version: 0.7.110-1+b2
Severity: important
Tags: security
Usertags: ldpath


During a review of the Debian archive, I've found your package to
contain a script that can be abused by an attacker to execute arbitrary

The vulnerability is introduced by an insecure change to
LD_LIBRARY_PATH, and environment variable used by to look for
libraries on a directory other than the standard paths.

Vulnerable code follows:

/usr/lib/dropbox/dropboxd line 9:

When there's an empty item on the colon-separated list of
LD_LIBRARY_PATH, treats it as '.' (i.e. CWD/$PWD.)
If the given script is executed from a directory where a potential,
local, attacker can write files to, there's a chance to exploit this

This vulnerability has been assigned the CVE id CVE-2010-3354. Please make sure
you mention it when forwarding this report to upstream and when fixing
this bug (everywhere: upstream and here at Debian.)

I've already tried to contact upstream via their tickets system,
without response so far.
