openssl vulnerabilities
==========================================================================

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

- 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. One of the patch backports for
Ubuntu 10.04 LTS caused a regression for certain applications. This update
fixes the problem.

We apologize for the inconvenience.

Original advisory details:

J?ri Aedla discovered that OpenSSL incorrectly handled invalid DTLS
fragments. A remote attacker could use this issue to cause OpenSSL to

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?bert and Ivan Fratri? 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

After a standard system update you need to reboot your computer to make all
the necessary changes.
