Comment 8 Anthony Basile gentoo-dev 2016-09-07 08:52:46 UTC
@remaining arch team.  please halt, we need to start over with 7.50.2 because of an update to the fix to the cert vulnerability, see bug #592974.

@security team.  this bug is obsolete wrt to bug #592974.  its the same vulnerability but the original fix was incomplete.  i won't change the status on this bug report, but please act accordingly.
Comment 9 Anthony Basile gentoo-dev 2016-09-15 08:29:32 UTC
@arch teams, we need to start over with bug #593716 as yet another vulnerability was found.

CVE-2016-5421 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-5421):
  Use-after-free vulnerability in libcurl before 7.50.1 allows attackers to
  control which connection is used or possibly have unspecified other impact
  via unknown vectors.

CVE-2016-5420 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-5420):
  curl and libcurl before 7.50.1 do not check the client certificate when
  choosing the TLS connection to reuse, which might allow remote attackers to
  hijack the authentication of the connection by leveraging a previously
  created connection with a different client certificate.

CVE-2016-5419 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-5419):
  curl and libcurl before 7.50.1 do not prevent TLS session resumption when
  the client certificate has changed, which allows remote attackers to bypass
  intended restrictions by resuming a session.
