Description Chris Reffett (RETIRED) gentoo-dev Security 2013-08-05 23:26:54 UTC
From ${URL}:

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

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:


In summary, filezilla is also affected by CVE-2013-4852. Nothing from upstream yet.
Comment 1 Bernard Cafarelli gentoo-dev 2013-08-07 08:40:29 UTC
Upstream released 3.7.2 to address the vulnerability, I just added it to portage

Arches, please test and mark stable =net-ftp/filezilla-3.7.2, thanks!

Special test: if anyone has a system with gnutls-2.x, a FTPES server with TLS to test filezilla against, it would be great (to confirm gnutls-3.x is not needed anymore for this case, see #431404)
If not, this should not block stabilization (I can add a warning for it in the ebuild)

Comment 6 Bernard Cafarelli gentoo-dev 2013-08-09 08:08:39 UTC
Additional CVEs came in the wake of this one: CVE-2013-4206, CVE-2013-4207, CVE-2013-4208

filezilla-3.7.3 was released to address these (just added to tree), should we stabilize it in this bug or start a new one? (sorry arches for the double stabilization)
Comment 7 Chris Reffett (RETIRED) gentoo-dev Security 2013-08-23 14:36:13 UTC
If those CVEs were released as a group, please file a separate bug. GLSA request filed for this one.
