Subject: filezilla: CVE-2013-4852: PuTTY SSH handshake heap overflow
Date: Mon, 05 Aug 2013 17:37:22 +0200
Package: filezilla
Severity: grave
Tags: security patch upstream

Hi,

the following vulnerability was published for putty, but filezilla
embedds putty source:

CVE-2013-4852[0]:
PuTTY SSH handshake heap overflow

See the advisory [1] for details referring to putty commit [2].
AFAICS filezilla embedding putty in vulnerable version is used in
build for fzsftp. See [3] for the corresponding bugreport for putty
itself.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

For further information see:

[0] http://security-tracker.debian.org/tracker/CVE-2013-4852
[1] http://www.search-lab.hu/advisories/secadv-20130722
[2] http://svn.tartarus.org/sgt?view=revision&sortby=date&revision=9896
[3] http://bugs.debian.org/718779

Please adjust the affected versions in the BTS as needed.

Regards,
Salvatore

==============

Personal comment: it would be great if software embedded other
software/code (e.g. libxml2/expat are common ones, as is zlib and
other compressors) could be listed in a semi standard fashion in the
source code (e.g. maybe an "EMBEDDED.txt" or something?) along with
the date/version that was embedded.
