Secure testing team - Apr 2009 - Bug#525078: insufficient path escaping when opening fies

Package: amule
Version: 2.2.4-1+b1
Severity: normal
Tags: security upstream

   src/DownloadListCtrl.cpp does the following (code edited for
clarification):

command = wxT("xterm -T \"aMule Preview\" -iconic -e mplayer
''$file''");
[...]
wxString rawFileName = file->GetFullName().GetRaw();
command.Replace(wxT("$file"), rawFileName);
[...]
wxExecute(command, wxEXEC_ASYNC, p);

   Although file->GetFullName() is sanitised by removing :/<> and
probably other characters, the single tick ('') is neither filtered
away nor escaped. Thus it is possible to craft a file name that
passes remotely defined arguments to the video player.

   A side effect is that it is impossible to open a downloaded file that
has a "''" character in its name.
