+  <title>Two buffer overflows in lftp</title>
+  <synopsis>
+    Two buffer overflow problems are found in lftp that, in case the user visits
+    a malicious ftp server, could lead to malicious code being executed.

+    lftp is a multithreaded command-line based FTP client. It allows you to
+    execute multiple commands simultaneously or in the background. If features
+    mirroring capabilities, resuming downloads, etc.

+    Two buffer overflows exist in lftp. Both can occur when the user connects to
+    a malicious web server using the HTTP or HTTPS protocol and issues lftp's
+    "ls" or "rels" commands.
+    </p>

+    Ulf Harnhammar explains:
+    </p>
+    <p>
+    Technically, the problem lies in the file src/HttpDir.cc and the
+    functions try_netscape_proxy() and try_squid_eplf(), which both
+    have sscanf() calls that take data of an arbitrary length and
+    store it in a char array with 32 elements. (Back in version 2.3.0,
+    the problematic code was located in some other function, but the
+    problem existed back then too.) Depending on the HTML document in the 
+    specially prepared directory, buffers will be overflown in either one 
+    function or the other.

+    When a user issues "ls" or "rels" on a malicious server, the tftp
+    application can be tricked into running arbitrary code on the user his
+    machine.

+    There is no workaround available.

+    All Gentoo users who have net-ftp/lftp installed should update to use
+    version 2.6.0 or higher using these commands:

+    <code>
+    # emerge sync
+    # emerge -pv '&gt;=net-ftp/lftp-2.6.10'
+    # emerge '&gt;=net-ftp/lftp-2.6.10'
+    # emerge clean</code>
