Description Vasyl Kaigorodov 2014-08-05 14:12:24 UTC

Upstream [1] reports:
...
A bug in nginx SMTP proxy was found, which allows an attacker in a
privileged network position to inject commands into SSL sessions started
with the STARTTLS command, potentially making it possible to steal
sensitive information sent by clients (CVE-2014-3556).

The problem affects nginx 1.5.6 - 1.7.3.

The problem is fixed in nginx 1.7.4, 1.6.1.

Patch for the problem can be found here:

Comment 1 Vasyl Kaigorodov 2014-08-05 14:12:39 UTC

Created nginx tracking bugs for this issue:

Affects: epel-7 [bug 1126892]

Comment 2 Vasyl Kaigorodov 2014-08-05 15:36:23 UTC

Statement:

This issue did not affect the versions of nginx as shipped with Red Hat Software Collections 1 for Red Hat Enterprise Linux 6 and 7.

Comment 5 Tomas Hoger 2014-08-05 16:03:46 UTC

nginx 1.6 is in Fedora 21 / Rawhide.  Update to version 1.6.1 was already built by the maintainer.

Comment 6 Warren Togami 2014-08-18 23:43:46 UTC

This is now fixed?

Comment 7 Peter Borsa 2015-03-24 13:07:07 UTC

Hi!

I suppose it's fixed in 1.6.x because there is a stable version (nginx-1.6.2-4.fc21) and

"* Tue Aug 05 2014 Jamie Nguyen <jamielinux> - 1:1.6.1-1
- update to upstream release 1.6.1
- (#1126891) CVE-2014-3556: SMTP STARTTLS plaintext injection flaw"

Can we close this issue?
