Summary:

json-c could be made to crash or consume CPU if it processed a specially
crafted JSON document.

Software Description:
- json-c: JSON manipulation library

Details:

Florian Weimer discovered that json-c incorrectly handled buffer lengths.
An attacker could use this issue with a specially-crafted large JSON
document to cause json-c to crash, resulting in a denial of service.
(CVE-2013-6370)

Florian Weimer discovered that json-c incorrectly handled hash arrays. An
attacker could use this issue with a specially-crafted JSON document to
cause json-c to consume CPU resources, resulting in a denial of service.
(CVE-2013-6371)

Update instructions:

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

Ubuntu 14.04 LTS:
libjson0 0.11-3ubuntu1.2

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?ri 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?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
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

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