openssl regression
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS

Summary:

USN-2232-1 introduced a regression in OpenSSL.

Software Description:
- openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

USN-2232-1 fixed vulnerabilities in OpenSSL. The upstream fix for
CVE-2014-0224 caused a regression for certain applications that use
tls_session_secret_cb, such as wpa_supplicant. This update fixes the
problem.

Original advisory details:

 J=C3=BCri Aedla discovered that OpenSSL incorrectly handled invalid DTLS
 fragments. A remote attacker could use this issue to cause OpenSSL to
 crash, resulting in a denial of service, or possibly execute arbitrary
 code. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and
 Ubuntu 14.04 LTS. (CVE-2014-0195)
  Imre Rad discovered that OpenSSL incorrectly handled DTLS recursions. A
 remote attacker could use this issue to cause OpenSSL to crash, resulting
 in a denial of service. (CVE-2014-0221)
  KIKUCHI Masashi discovered that OpenSSL incorrectly handled certain
 handshakes. A remote attacker could use this flaw to perform a
 man-in-the-middle attack and possibly decrypt and modify traffic.
 (CVE-2014-0224)
  Felix Gr=C3=B6bert and Ivan Fratri=C4=87 discovered that OpenSSL incorrectly handled
 anonymous ECDH ciphersuites. A remote attacker could use this issue to
 cause OpenSSL to crash, resulting in a denial of service. This issue only
 affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS.
 (CVE-2014-3470)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  libssl1.0.0                     1.0.1f-1ubuntu2.3

Ubuntu 13.10:
  libssl1.0.0                     1.0.1e-3ubuntu1.5

Ubuntu 12.04 LTS:
  libssl1.0.0                     1.0.1-4ubuntu5.15
