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

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

– Ubuntu 14.04 LTS
– Ubuntu 13.10
– Ubuntu 12.04 LTS
– Ubuntu 10.04 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
renegotiation, such as PostgreSQL. This update fixes the problem.

Original advisory details:

Jüri 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 Gröbert and Ivan Fratrić 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)
